Ubuntu 14.04 LTS : Libtasn1 vulnerability (USN-2957-1)

medium Nessus Plugin ID 90856

Synopsis

The remote Ubuntu host is missing a security update.

Description

Pascal Cuoq and Miod Vallat discovered that Libtasn1 incorrectly handled certain malformed DER certificates. A remote attacker could possibly use this issue to cause applications using Libtasn1 to hang, resulting in a denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
