SUSE CVE-2025-5372

A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the sshkdf function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success-the function may mistakenl...

CVE-2025-4877

There's a vulnerability in the libssh package where when a libssh consumer passes in an unexpectedly large input buffer to sshgetfingerprinthash function. In such cases the bintobase64 function can experience an integer overflow leading to a memory under allocation, when that happens it's possibl...
