CVE-2014-1959 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:N

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.
