CVE-2016-7444

Priority
Description
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.
