Synopsis
The remote Ubuntu host is missing a security-related patch.Description
USN-1904-1 fixed vulnerabilities in libxml2. The update caused a regression for certain users. This update fixes the problem.We apologize for the inconvenience.

If a user or automated system were tricked into opening a specially crafted document, an attacker could possibly obtain access to arbitrary files or cause resource consumption. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 12.10.
(CVE-2013-0339)
It was discovered that libxml2 incorrectly handled documents that end abruptly. 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. (CVE-2013-2877).
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.
