Ubuntu 14.04 LTS : Libtasn1 vulnerability (USN-2604-1)

medium Nessus Plugin ID 83344

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2604-1 advisory.

 Hanno Bck discovered that Libtasn1 incorrectly handled certain ASN.1 data. A remote attacker could possibly exploit this with specially crafted ASN.1 data and cause applications using Libtasn1 to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
