Debian DSA-3884-1 : gnutls28 - security update

high Nessus Plugin ID 100852
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Hubert Kario discovered that GnuTLS, a library implementing the TLS and SSL protocols, does not properly decode a status response TLS extension, allowing a remote attacker to cause an application using the GnuTLS library to crash (denial of service).

Solution

Upgrade the gnutls28 packages.

For the stable distribution (jessie), this problem has been fixed in version 3.3.8-6+deb8u6.

For the upcoming stable distribution (stretch), this problem has been fixed in version 3.5.8-5+deb9u1.
