Vulnerability from github – Published: 2026-03-26 21:31 – Updated: 2026-03-26 21:31

Details

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 to try and access dangerous files, such as block devices or large system files, which can disrupt normal operations.

Severity ?

3.3 (Low)
