Vulnerability Title
Gnutls: gnutls: security bypass allows acceptance of revoked server certificates via crafted ocsp response
Source: NVD (National Vulnerability Database)
Vulnerability Description
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted Online Certificate Status Protocol (OCSP) response during a TLS handshake. Due to a logic error in how gnutls processes multi-record OCSP responses, a client with OCSP verification enabled may incorrectly accept a revoked server certificate, potentially leading to a compromise of trust.
