CWE-310  (opens in a new tab)

How to fix?

Upgrade gnutls to version 1.4.2 or higher.

Overview

Affected versions of this package are vulnerable to Cryptographic Issues. The _gnutls_x509_oid2mac_algorithm function in lib/gnutls_algorithms.c in GnuTLS before 1.4.2 allows remote attackers to cause a denial of service (crash) via a crafted X.509 certificate that uses a hash algorithm that is not supported by GnuTLS, which triggers a NULL pointer dereference.
