Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 : libxml2 vulnerability (USN-1153-1)

High Nessus Plugin ID 55168


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


Chris Evans discovered that libxml2 incorrectly handled memory allocation. If an application using libxml2 opened a specially crafted XML file, an attacker could cause a denial of service or possibly execute code as the user invoking the program.

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.


Update the affected libxml2 package.
