Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
USN-2098-1 fixed a vulnerability in LibYAML. The security fix used
introduced a regression that caused parsing failures for certain valid
YAML files. This update fixes the problem.
We apologize for the inconvenience.
Florian Weimer discovered that LibYAML incorrectly handled certain
large yaml documents. An attacker could use this issue to cause
LibYAML to crash, resulting in a denial of service, or possibly
execute arbitrary code.
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 libyaml-0-2 package.
