Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS : libxml2 vulnerability (USN-2389-1)
Medium Nessus Plugin ID 78698
Synopsis
The remote Ubuntu host is missing a security-related patch.
Description
It was discovered that libxml2 would incorrectly perform entity substitution even when requested not to. If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly cause resource consumption, 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.
