SSL: GnuTLS Certificate Verification Policy Bypass
This signature detects attempts to exploit a known vulnerability in the GnuTLS Certificate. The vulnerability is due to an error in validating certificates. A remote attacker can employ this vulnerability to bypass certificate validation performed by an application using a vulnerable version of the GnuTLS library.
Extended Description
lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not properly handle unspecified errors when verifying X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
