==========================================================================
Ubuntu Security Notice USN-2461-1
January 12, 2015

libyaml vulnerability
==========================================================================

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Applications using LibYAML could be made to crash if they received
specially crafted input.

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

Details:

Stanisław Pitucha and Jonathan Gray discovered that LibYAML did not
properly handle wrapped strings. An attacker could create specially
crafted YAML data to trigger an assert, causing a denial of service.

Update instructions:

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

Ubuntu 14.10:
  libyaml-0-2                     0.1.6-1ubuntu0.1

Ubuntu 14.04 LTS:
  libyaml-0-2                     0.1.4-3ubuntu3.1

Ubuntu 12.04 LTS:
  libyaml-0-2                     0.1.4-2ubuntu0.12.04.4

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