The remote Debian host is missing a security-related update.


Kurt Roeckx discovered that decoding a specific certificate with very long DistinguishedName (DN) entries leads to double free. A remote attacker can take advantage of this flaw by creating a specially crafted certificate that, when processed by an application compiled against GnuTLS, could cause the application to crash resulting in a denial of service.


Upgrade the gnutls28 packages.

For the stable distribution (jessie), this problem has been fixed in version 3.3.8-6+deb8u2.
