Name of the Vulnerable Software and Affected Versions libssh affected versions not specified Description A flaw exists in libssh that allows local man-in-the-middle attacks, security downgrades of SSH Secure Shell connections, and manipulation of trusted host information. This poses a risk to the...
EUVD-2026-16328
A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service DoS by causing the system t...
EUVD-2026-16332
A flaw was found in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could craft specific hostnames that when processed by the matchpattern function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion,...
Tenable Security Center < 6.8.0 Multiple Vulnerabilities (TNS-2026-07)
According to its self-reported version, the Tenable Security Center running on the remote host is prior to 6.8.0. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2026-07 advisory. - A flaw was found in the libssh implements abstract layer for message digest MD...
UBUNTU-CVE-2026-0967
A flaw was found in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could craft specific hostnames that when processed by the matchpattern function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion,...
Astra Linux – Vulnerability in libssh
A flaw was discovered in the key export functionality of libssh. The issue arises from an internal function responsible for converting cryptographic keys into serialized formats. During error handling, a memory structure is freed but not cleared properly. This can lead to a double-free issue if...
Astra Linux – Vulnerability in libssh
A flaw was discovered in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange KEX process, a failure in cryptographic functions may lead to a NULL pointer being dereferenced. This issue can cause the client or server to crash...
libssh: Invalid return code for chacha20 poly1305 with OpenSSL backend
A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with th...
JLSEC-2025-332 A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library
A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized cipher context. This occurs because the OpenSSL error code returned aliases with th...
JLSEC-2025-100 A flaw was found in the SFTP server message decoding logic of libssh
A flaw was found in the SFTP server message decoding logic of libssh. The issue occurs due to an incorrect packet length check that allows an integer overflow when handling large payload sizes on 32-bit systems. This issue leads to failed memory allocation and causes the server process to crash,...
JLSEC-2025-97 A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the...
A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the sshkdf function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenl...
