Package : libssh
CVE ID : CVE-2023-1667 CVE-2023-2283
Debian Bug : 1035832

Two security issues have been discovered in libssh, a tiny C SSH library:

CVE-2023-1667

Philip Turnbull discovered a NULL pointer dereference which could
result in denial of service.

CVE-2023-2283

Kevin Backhouse discovered that pki_verify_data_signature() may
fail to correctly validate authentication in memory pressure
situations.





For the stable distribution (bullseye), these problems have been fixed in
version 0.9.7-0+deb11u1.

We recommend that you upgrade your libssh packages.
