CVE-ID : CVE-2016-7444
Package : lib32-gnutls
Type : certificate verification bypass
Remote : Yes
Link : https://wiki.archlinux.org/index.php/CVE
The package lib32-gnutls before version 3.4.15-1 is vulnerable to
certificate verification bypass.
Upgrade to 3.4.15-1.
The problem has been fixed upstream in version 3.4.15.
None.
Incorrect length validation on gnutls’s gnutls_ocsp_resp_check_crt
method can allow an attacker to use a OCSP response for a different
certificate (but from the same CA) to continue using a revoked
certificate. This can happen if the serial from the revoked certificate
is a prefix of the other one, and the additional bytes happen to be
equal on the system doing the verification.
A remote attacker is able to bypass certificate verification and
continue using a revoked certificate under certain circumstances.
