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
