Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : libyaml-libyaml-perl vulnerability (USN-2461-2)
Medium Nessus Plugin ID 80473
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionStanislaw Pitucha and Jonathan Gray discovered that libyaml-libyaml-perl did not properly handle wrapped strings. An attacker could create specially crafted YAML data to trigger an assert, causing 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 libyaml-libyaml-perl package.
