Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : libxml2 vulnerability (USN-640-1)
Medium Nessus Plugin ID 34094
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionAndreas Solberg discovered that libxml2 did not handle recursive entities safely. If an application linked against libxml2 were made to process a specially crafted XML document, a remote attacker could exhaust the system's CPU resources, leading to 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.
SolutionUpdate the affected packages.
