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-2427-1 advisory.

Hanno Bck discovered that Libksba incorrectly handled certain S/MIME messages or ECC based OpenPGP data.
An attacker could use this issue to cause Libksba 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.
