Ubuntu 12.04 LTS / 14.04 LTS / 15.04 / 15.10 : libxml2 vulnerabilities (USN-2875-1)

High Nessus Plugin ID 88019

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

It was discovered that libxml2 incorrectly handled certain malformed documents. If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause libxml2 to crash, 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

Update the affected libxml2 package.
