Ubuntu USN-2098-1 introduced a regression in LibYAML.
==========================================================================
Ubuntu Security Notice USN-2098-2
February 13, 2014

libyaml regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

USN-2098-1 introduced a regression in LibYAML.

Software Description:
- libyaml: Fast YAML 1.1 parser and emitter library

Details:

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.

Original advisory details:

 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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.10:
  libyaml-0-2                     0.1.4-2ubuntu0.13.10.2

Ubuntu 12.10:
  libyaml-0-2                     0.1.4-2ubuntu0.12.10.2

Ubuntu 12.04 LTS:
  libyaml-0-2                     0.1.4-2ubuntu0.12.04.2

After a standard system update you need to restart applications using
LibYAML to make all the necessary changes.
