Vulnerability Summary for CVE-2016-7444
Original release date: 09/27/2016
Last revised: 09/28/2016
Source: US-CERT/NIST
Overview

The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.

https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2016-7444 lists all versions pre 3.4.15 as vulnerable so 26 (2.12) should be assumed to be vulnerable.
https://people.canonical.com/~ubuntu-security/cve/2016/CVE-2016-7444 lists gnutls28 as vulnerable but does not mention gnutls26.

[Marc Deslauriers (mdeslaur)]

The vulnerable code isn't in 2.12.x, so the gnutls26 package isn't vulnerable.
