Gnutls: gnutls: remote denial of service via crafted clienthello with invalid psk binder
Summary
A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition.

Title
Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()
Summary
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.
Severity ?
6.7 (Medium)

Title
Libarchive: a null pointer dereference vulnerability exists in the acl parser of libarchive
Summary
A flaw was found in libarchive. A NULL pointer dereference vulnerability exists in the ACL parsing logic, specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such as a bare "d" or "default" tag without subsequent fields), the function fails to perform adequate validation before advancing the pointer. An attacker can exploit this by providing a maliciously crafted archive, causing an application utilizing the libarchive API (such as bsdtar) to crash, resulting in a Denial of Service (DoS).
Severity ?

Title
Util-linux: util-linux: access control bypass due to improper hostname canonicalization
Summary
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.

Title
P11-kit: p11-kit: null dereference via c_derivekey with specific null parameters
Summary
A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states.

Title
Libssh: libssh: denial of service due to malformed sftp message
Summary
A flaw was found in libssh in which a malicious SFTP (SSH File Transfer Protocol) server can exploit this by sending a malformed 'longname' field within an `SSH_FXP_NAME` message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can cause unexpected behavior or lead to a denial of service (DoS) due to application crashes.

Title
Libssh: libssh: denial of service via inefficient regular expression processing
Summary
A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client.

Title
Libssh: buffer underflow in ssh_get_hexa() on invalid input
Summary
The API function `ssh_get_hexa()` is vulnerable, when 0-lenght
input is provided to this function. This function is used internally
in `ssh_get_fingerprint_hash()` and `ssh_print_hexa()` (deprecated),
which is vulnerable to the same input (length is provided by the
calling application).
The function is also used internally in the gssapi code for logging
the OIDs received by the server during GSSAPI authentication. This
could be triggered remotely, when the server allows GSSAPI authentication
and logging verbosity is set at least to SSH_LOG_PACKET (3). This
could cause self-DoS of the per-connection daemon process.
Severity ?
6.5 (Medium)

Gnutls: gnutls: remote denial of service via crafted clienthello with invalid psk binder
Summary
A flaw was found in gnutls. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted ClientHello message with an invalid Pre-Shared Key (PSK) binder value during the TLS handshake. This can lead to a NULL pointer dereference, causing the server to crash and resulting in a remote Denial of Service (DoS) condition.

Title
Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()
Summary
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.
Severity ?

Title
Libarchive: a null pointer dereference vulnerability exists in the acl parser of libarchive
Summary
A flaw was found in libarchive. A NULL pointer dereference vulnerability exists in the ACL parsing logic, specifically within the archive_acl_from_text_nl() function. When processing a malformed ACL string (such as a bare "d" or "default" tag without subsequent fields), the function fails to perform adequate validation before advancing the pointer. An attacker can exploit this by providing a maliciously crafted archive, causing an application utilizing the libarchive API (such as bsdtar) to crash, resulting in a Denial of Service (DoS).

Title
Util-linux: util-linux: access control bypass due to improper hostname canonicalization
Summary
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access.

Title
Libssh: libssh: denial of service via inefficient regular expression processing
Summary
A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion, resulting in a Denial of Service (DoS) for the client.

Title
Libssh: libssh: denial of service due to malformed sftp message
Summary
A flaw was found in libssh in which a malicious SFTP (SSH File Transfer Protocol) server can exploit this by sending a malformed 'longname' field within an `SSH_FXP_NAME` message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can cause unexpected behavior or lead to a denial of service (DoS) due to application crashes.

Libssh: improper sanitation of paths received from scp servers
Summary
A malicious SCP server can send unexpected paths that could make the
client application override local files outside of working directory.
This could be misused to create malicious executable or configuration
files and make the user execute them under specific consequences.
This is the same issue as in OpenSSH, tracked as CVE-2019-6111.

Title
Libssh: buffer underflow in ssh_get_hexa() on invalid input
Summary
The API function `ssh_get_hexa()` is vulnerable, when 0-lenght
input is provided to this function. This function is used internally
in `ssh_get_fingerprint_hash()` and `ssh_print_hexa()` (deprecated),
which is vulnerable to the same input (length is provided by the
calling application).
The function is also used internally in the gssapi code for logging
the OIDs received by the server during GSSAPI authentication. This
could be triggered remotely, when the server allows GSSAPI authentication
and logging verbosity is set at least to SSH_LOG_PACKET (3). This
could cause self-DoS of the per-connection daemon process.
Severity ?

Title
P11-kit: p11-kit: null dereference via c_derivekey with specific null parameters
Summary
A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states.
