NVD Description

Note: Versions mentioned in the description apply only to the upstream libssh-devel package and not the libssh-devel package as distributed by RHEL.

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.
