Synopsis

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

Description

It was discovered that libxml2 incorrectly handled XML entity expansion. An attacker could use this flaw to cause libxml2 to consume large amounts of resources, 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.
