Kerentanan Inefficient Regular Expression Complexity pada libssh, redhat enterprise linux. Skor CVSS 3.1 5.5 (Medium) menurut NVD.

Deskripsi (NVD)

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.
