Title
universal-ctags V Language v.c parseExprList recursion
Summary
A weakness has been identified in universal-ctags ctags up to 6.2.1. The affected element is the function parseExpression/parseExprList of the file parsers/v.c of the component V Language Parser. Executing a manipulation can lead to uncontrolled recursion. It is possible to launch the attack on the local host. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

Title
Mongod can run out of stack memory when expressions create deeply nested documents

Title
net: Stack Overflow with Ping (to own IP Address) via Shell
Summary
Issuing an ICMP ping via the `net ping` shell command to a device's own IPv4 address causes the network stack to recursively re-enter the input path on the same system work-queue stack. Because the destination is recognized as a local address, both the echo request and the resulting echo reply are processed inline before the current frame returns. The nested input-path frames exceed the work-queue stack and trigger a stack overflow.

Title
Denial of Service in Python Protobuf
Summary
A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages.
Due to missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply nested Any structures that bypass the intended recursion limit, eventually exhausting Python’s recursion stack and causing a RecursionError.
Severity

Title
Libxml2: libxml2: denial of service via uncontrolled recursion in xml catalog processing
Summary
A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.

Title
Libxml2: unbounded relaxng include recursion leading to stack overflow
Summary
A flaw was identified in the RelaxNG parser of libxml2 related to how external schema inclusions are handled. The parser does not enforce a limit on inclusion depth when resolving nested <include> directives. Specially crafted or overly complex schemas can cause excessive recursion during parsing. This may lead to stack exhaustion and application crashes, creating a denial-of-service risk.

Title
SurrealDB before 2.2.2 Memory Exhaustion via Nested Functions
Summary
SurrealDB before 2.2.2 with scripting enabled fails to properly enforce recursion limits when native functions contain embedded JavaScript that issues new queries. Authenticated attackers can bypass the recursion limit by chaining native and JavaScript function calls to trigger infinite recursion and exhaust server memory.

Title
MuPDF < 1.27.0-rc1 Stack Exhaustion DoS via EPUB CSS Rendering
Summary
MuPDF before 1.27.0-rc1 contains an uncontrolled recursion vulnerability in the EPUB CSS rendering engine that allows remote attackers to cause a denial of service by supplying a maliciously crafted EPUB file with deeply nested HTML elements and inline CSS styles. The function value_from_inheritable_property() in css-apply.c recurses through the CSS property inheritance chain without a depth limit, exhausting the process stack and causing a crash in any application using MuPDF for EPUB rendering.

Title
Magick's failure to limit MVG mutual references forming a loop
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-12, Magick fails to check for circular references between two MVGs, leading to a stack overflow. This is a DoS vulnerability, and any situation that allows reading the mvg file will be affected. Version 7.1.2-12 fixes the issue.

Mitigation
Implementation
Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
Mitigation
Implementation
Increase the stack size.
CAPEC-230: Serialized Data with Nested Payloads
Applications often need to transform data in and out of a data format (e.g., XML and YAML) by using a parser. It may be possible for an adversary to inject data that may have an adverse effect on the parser when it is being processed. Many data format languages allow the definition of macro-like structures that can be used to simplify the creation of complex structures. By nesting these structures, causing the data to be repeatedly substituted, an adversary can cause the parser to consume more resources while processing, causing excessive memory consumption and CPU utilization.
CAPEC-231: Oversized Serialized Data Payloads
An adversary injects oversized serialized data payloads into a parser during data processing to produce adverse effects upon the parser such as exhausting system resources and arbitrary code execution.
