GnuTLS X.509 Version 1 Intermediate Certificate Policy Bypass (CVE-2014-1959)

A policy-bypass vulnerability has been found in GnuTLS. The vulnerability is due to an error in lib/x509/verify.c where an X.509 version 1 certificate is incorrectly treated as an intermediate CA certificate. A remote attacker could exploit this vulnerability to bypass certificate validation...

CVE-2014-1959

lib/x509/verify.c in GnuTLS before 3.1.21 and 3.2.x before 3.2.11 treats version 1 X.509 certificates as intermediate CAs, which allows remote attackers to bypass intended restrictions by leveraging a X.509 V1 certificate from a trusted CA to issue new certificates...
