CVE-2026-0966:
Linux Debian vulnerability analysis and mitigation
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.
