RHSA-2026:54395
Vulnerability from csaf_redhat - Published: 2026-08-12 14:37 - Updated: 2026-10-03 10:01A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier (URI) that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI's intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.

A flaw was found in the shell-quote component. The quote() function did not properly validate object-token inputs, allowing line terminators to pass unescaped into the output. A remote attacker could exploit this vulnerability by providing specially crafted input, which a POSIX shell would interpret as a command separator. This could lead to command injection, enabling the attacker to execute arbitrary code on the system.
A flaw was found in kafka-python. A malicious or machine-in-the-middle broker could exploit a denial-of-service vulnerability during SCRAM authentication. By providing an excessively large iteration count, the broker can cause the client's event loop to freeze. This prevents critical operations such as sending messages, polling for new messages, and maintaining heartbeats, ultimately leading to consumer group eviction and persistent connection failures.
A flaw was found in form-data, a library for creating readable multipart/form-data streams. A remote attacker can exploit this vulnerability by injecting carriage return (CR), line feed (LF), or double-quote (") characters into the `field` argument of `FormData#append` or the `filename` option. This allows the attacker to inject additional headers or smuggle entire additional multipart parts into requests, potentially enabling them to add or override form fields and compromise data integrity.
A flaw was found in brace-expansion. An attacker can exploit a vulnerability in the `expand()` function by providing a specially crafted string. This string, containing consecutive non-expanding brace groups, can trigger exponential-time complexity, leading to significant CPU consumption and event-loop blocking. This can result in a Denial of Service (DoS) for the affected system.
A flaw was found in fast-uri. This vulnerability occurs because fast-uri fails to properly convert Unicode (Internationalized Domain Name - IDN) hostnames for HTTP-family URLs. This can lead to a situation where security policies, such as denylists or redirect validations, are bypassed when applications use fast-uri to enforce these policies before passing the URL to another parser. A remote attacker could exploit this to circumvent security controls and potentially access unauthorized resources or perform malicious redirects.
A flaw was found in Red Hat Quay's repository-level mirror configuration feature. The POST and PUT handlers in endpoints/api/mirror.py accept an external_reference parameter without SSRF validation, unlike the organization-level mirror handlers which apply validate_external_registry_url(). A repository administrator can supply a crafted hostname that causes the Quay mirror worker to make requests via Skopeo to internal network services, cloud metadata endpoints, or other resources not intended to be reachable from the Quay application.
A flaw was found in golang.org/x/net/idna. ToASCII and ToUnicode incorrectly accept Punycode-encoded labels that decode to an ASCII-only hostname (for example, xn--example-.com returns example.com instead of an error). Applications that validate the ASCII form then convert to Unicode may grant access to a restricted hostname the ASCII check would have rejected.
A flaw was found in golang.org/x/crypto/ssh. A remote attacker could exploit this vulnerability when an SSH server authentication callback returned a PartialSuccessError with non-nil permissions. This flaw caused these permissions to be silently discarded, potentially bypassing certificate restrictions, such as a force-command, after a second authentication factor succeeded. This could lead to unauthorized command execution or access.
A flaw was found in golang.org/x/crypto/ssh. The RSA and DSA public key parsers in the affected component did not enforce size limits on key parameters. This vulnerability allows an unauthenticated client to provide a crafted public key with an excessively large modulus or DSA parameter during public key authentication. Successful exploitation could lead to a denial of service (DoS) due to prolonged CPU consumption during signature verification.
A flaw was found in golang.org/x/crypto/ssh. A remote malicious SSH peer can exploit this by sending unsolicited global request responses, which fills an internal buffer and blocks the connection's read loop. This prevents the associated resources from being released, leading to a resource leak per connection. The consequence is a Denial of Service (DoS) for the affected system.
A flaw was found in golang.org/x/crypto/ssh. The Verify() method, responsible for FIDO/U2F security key types, did not properly check for user presence. This allowed signatures to be accepted without requiring a physical touch on the hardware security key. As a result, an attacker could potentially use a hardware security key in an unattended manner, bypassing a critical security control designed to ensure user intent.
A flaw was found in golang.org/x/crypto/ssh/agent. When a key was added to a remote agent, security restrictions, known as constraint extensions, were not properly processed during the request. This allowed these restrictions to be silently removed when keys were forwarded, leading to the unrestricted use of the key on the remote host. This vulnerability could enable an attacker to bypass intended security controls and perform unauthorized actions.
A flaw was found in golang.org/x/crypto/ssh. SSH servers configured to use CertChecker as a public key callback, without explicitly setting IsUserAuthority or IsHostAuthority, are vulnerable. A remote attacker can exploit this by presenting a specially crafted certificate, causing the server to panic and resulting in a Denial of Service (DoS).
A flaw was found in golang.org/x/crypto/ssh/knownhosts. This vulnerability occurs because the system did not correctly check for the revocation status of a SignatureKey belonging to a Certificate Authority (CA). A remote attacker could potentially exploit this by presenting a revoked key, leading to the system accepting it as valid. This could allow an attacker to bypass security checks and potentially gain unauthorized access or spoof legitimate entities.
A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response, even if only a partial read was requested, or when draining the connection after a partial decompression. This can lead to a Denial of Service (DoS) condition.
A flaw was found in the `sanitize-html` library. Under its default configuration, an attacker can embed malicious content within a disallowed `xmp` element. This vulnerability allows the attacker to bypass the HTML sanitization process, leading to stored Cross-Site Scripting (XSS). Successful exploitation can result in arbitrary code execution or information disclosure when a user views the affected content.
A flaw was found in golang.org/x/crypto/ssh. A remote attacker could send specially crafted inputs to the AES-GCM packet decoder. This could lead to an incorrectly placed cast from bytes to an integer, causing a server-side panic and resulting in a Denial of Service (DoS) for the affected system.
A flaw was found in Pillow prior to 12.3.0. When an uncompressed McIdas AREA image is loaded from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width. Pixel access such as Image.tobytes(), getpixel, convert, or save can then read beyond the mapped region, disclosing adjacent process memory or causing a fault.
A flaw was found in Pillow, a Python imaging library. When processing a specially crafted font file, the library's font compilation function does not adequately check for excessive memory allocation. This oversight allows a remote attacker to trigger an unreasonable consumption of system memory, leading to a denial of service (DoS) for the application.
A flaw was found in Pillow, a Python imaging library. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by providing a specially crafted BDF font file. The library's image processing function fails to properly validate dimensions from the font file, bypassing a critical security check designed to prevent excessive memory usage. This oversight can lead to the system consuming an unreasonable amount of memory, making it unavailable to legitimate users.
A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing a specially crafted GD 2.x image file. The GdImageFile._open() function reads image dimensions without proper validation, leading to excessive memory allocation. This can result in a Denial of Service (DoS) due to C-heap exhaustion.
A flaw was found in Podman, a tool for managing OCI containers and pods. A malicious container image can be crafted with an environment variable that has a key but no value, or an asterisk (*), to trick Podman. This vulnerability causes Podman to pass host environment variables into the container. Consequently, a malicious image could exfiltrate all Podman environment variables set in the session from which the container is launched, leading to information disclosure.
A flaw was found in Pillow prior to 12.3.0. The public RankFilter API can trigger a native heap out-of-bounds write when given a very large odd filter size. ImageFilter.RankFilter.filter() calls image.expand(size // 2, size // 2) before rank-filter size validation, and ImagingExpand() computes output dimensions with unchecked signed integer arithmetic. This can lead to denial of service and limited integrity impact via heap corruption.
A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit a vulnerability in the library's image processing functions, specifically when handling image coordinates near certain limits. This flaw, a native heap out-of-bounds write, could lead to a denial of service (DoS), making the affected system or application unavailable.
A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit a vulnerability in the PdfParser.PdfStream.decode() function when processing a crafted FlateDecode PDF stream. By providing a specially designed PDF file, the attacker could cause the application to exhaust available memory, leading to a denial of service (DoS).
A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing a specially crafted JPEG2000 image file. Due to incorrect calculation of memory requirements for image tiles, processing this file can lead to excessive memory consumption, resulting in a denial of service (DoS) through out-of-memory failures.
A flaw was found in Pillow, a Python imaging library. This vulnerability allows an attacker to trigger controlled native heap corruption by supplying an output image whose mode does not match the transform's declared output mode when using the ImageCms.ImageCmsTransform.apply API. This can lead to a denial of service (DoS) condition, making the affected system or application unavailable.
A flaw was found in js-yaml, a JavaScript YAML parser and dumper. A remote attacker could exploit this vulnerability by providing a specially crafted YAML document containing a chain of mappings with merge keys. This could cause the parser to consume excessive CPU resources, leading to a Denial of Service (DoS) for the affected system.
A flaw was found in pyasn1, a Python library for Abstract Syntax Notation One (ASN.1). The BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs. A remote attacker could exploit this by providing a specially crafted payload containing an OID with many arcs, leading to excessive CPU consumption and a denial of service (DoS) in applications that decode untrusted ASN.1 data. The corresponding encoders also exhibit this quadratic behavior when re-encoding attacker-supplied values.
A remote attacker can exploit this by providing specially crafted BER/CER/DER-encoded ASN.1 data with a large exponent in the REAL value. When the application subsequently prints, logs, compares, or performs arithmetic on the decoded value, this can cause excessive CPU and memory consumption, leading to a denial of service (DoS).
A flaw was found in nanoid, a JavaScript library for generating unique string IDs. A remote attacker could exploit an integer overflow vulnerability by providing a specific input to the `nanoid(size)` function. This issue causes the internal random number generator to become predictable, leading to the generation of identical identifiers for session tokens, security tokens (Cross-Site Request Forgery (CSRF) tokens), and API keys. Such predictability could allow an attacker to bypass security measures that rely on unique and random identifiers.

The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI\u0027s intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.",

By providing an excessively large iteration count, the broker can cause the client\u0027s event loop to freeze. This prevents critical operations such as sending messages, polling for new messages, and maintaining heartbeats, ultimately leading to consumer group eviction and persistent connection failures.",

A remote attacker can exploit this vulnerability by injecting carriage return (CR), line feed (LF), or double-quote (\") characters into the `field` argument of `FormData#append` or the `filename` option. This allows the attacker to inject additional headers or smuggle entire additional multipart parts into requests, potentially enabling them to add or override form fields and compromise data integrity.",

"text": "This is an Important impact flaw in the form-data library: a remote attacker can inject arbitrary headers or additional multipart parts via CRLF injection in field names or filenames, potentially overriding sensitive form fields and affecting data integrity.\n\nFor RHOAI and RHEL AI, severity is Moderate because affected versions appear only as a transitive npm dependency in RHOAI (dashboard, mod-arch plugins, MLflow UI) and RHEL AI 3.4 bootc images, and those products use fixed field names for uploads rather than passing untrusted user input as multipart field names or filenames. The documented exploit path is therefore not reachable in default deployments. Practical impact is limited to non-default or custom integrations that forward multipart requests using attacker-controlled field names.",

The expand() function exhibits exponential-time complexity when processing consecutive non-expanding brace groups. An attacker who can supply crafted input to expand(), directly or transitively via minimatch or glob, can cause significant CPU consumption and event-loop blocking, resulting in denial of service.

"text": "A flaw was found in fast-uri. This vulnerability occurs because fast-uri fails to properly convert Unicode (Internationalized Domain Name - IDN) hostnames for HTTP-family URLs. This can lead to a situation where security policies, such as denylists or redirect validations, are bypassed when applications use fast-uri to enforce these policies before passing the URL to another parser. A remote attacker could exploit this to circumvent security controls and potentially access unauthorized resources or perform malicious redirects.",

Applications that rely on `fast-uri` for URL parsing and policy enforcement, such as denylists or redirect validations, can be circumvented due to inconsistent handling of Unicode hostnames.

Implement firewall rules to allow connections only from trusted hosts or networks. This action limits the ability of malicious peers to send unsolicited global request responses. A restart of the affected service may be necessary for the new network rules to be applied effectively.",

When a key was added to a remote agent, security restrictions, known as constraint extensions, were not properly processed during the request.

This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response, even if only a partial read was requested, or when draining the connection after a partial decompression.

A malicious container image can be crafted with an environment variable that has a key but no value, or an asterisk (*), to trick Podman. This vulnerability causes Podman to pass host environment variables into the container. Consequently, a malicious image could exfiltrate all Podman environment variables set in the session from which the container is launched, leading to information disclosure.",

"text": "A flaw was found in Pillow prior to 12.3.0. The public RankFilter API can trigger a native heap out-of-bounds write when given a very large odd filter size. ImageFilter.RankFilter.filter() calls image.expand(size // 2, size // 2) before rank-filter size validation, and ImagingExpand() computes output dimensions with unchecked signed integer arithmetic. This can lead to denial of service and limited integrity impact via heap corruption.",

Expansion runs before size validation and ImagingExpand uses unchecked signed integer arithmetic for output dimensions. A remote attacker who can drive RankFilter with attacker-controlled sizes may crash the process or corrupt heap memory. Fixed in Pillow 12.3.0.",

Only code that calls ImageCmsTransform.apply() directly with a user-controlled output image whose mode does not match the transform can trigger the heap corruption. Audit your code for direct apply() calls to confirm.\n\nRHEL builds ship with ASLR, full RELRO/PIE, and FORTIFY_SOURCE by default, making escalation from crash to code execution much harder. For DoS containment, configure automatic service restart (Restart=always in systemd, or container restart policies) so the process recovers without manual intervention.",

"text": "A flaw was found in pyasn1, a Python library for Abstract Syntax Notation One (ASN.1). The BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs. A remote attacker could exploit this by providing a specially crafted payload containing an OID with many arcs, leading to excessive CPU consumption and a denial of service (DoS) in applications that decode untrusted ASN.1 data. The corresponding encoders also exhibit this quadratic behavior when re-encoding attacker-supplied values.",

A small crafted payload containing an OID with many arcs consumes excessive CPU per decode() call, allowing denial of service in applications that decode untrusted ASN.1 data (certificates, LDAP, SNMP, Kerberos).

A remote attacker could exploit an integer overflow vulnerability by providing a specific input to the `nanoid(size)` function. This issue causes the internal random number generator to become predictable, leading to the generation of identical identifiers for session tokens, security tokens (Cross-Site Request Forgery (CSRF) tokens), and API keys. Such predictability could allow an attacker to bypass security measures that rely on unique and random identifiers.",
