CVE-2026-0966
CVE-2026-0966 affects the libssh library with a buffer underflow in ssh_get_hexa() on invalid input. The issue occurs because ssh_get_hexa() is used by ssh_get_fingerprint_hash() and the deprecated ssh_print_hexa(), and also in gssapi logging. Remote triggering is possible when GSSAPI authenticat...

CVE-2026-0964 Libssh: improper sanitation of paths received from scp servers
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...

This can be exploited remotely by an attacker during GSSAPI Generic Security Service Application Program Interface authentication if the server's logging verbosity is se...
CVE-2026-0967: Inefficient Regular Expression Complexity
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,...
CVE-2026-0965: External Control of File Name or Path
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...
CVE-2026-0968: NULL Pointer Dereference
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 SSHFXPNAME message during a file listing operation. This missing null check can lead to reading beyond allocated memory on the heap. This can...
