Ubuntu Security Notice USN-2461-2
January 12, 2015

libyaml-libyaml-perl vulnerability

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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


Applications using libyaml-libyaml-perl could be made to crash if
they received specially crafted input.

Software Description:
- libyaml-libyaml-perl: Perl interface to libyaml, a YAML implementation


Stanisław 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.

Update instructions:

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

Ubuntu 14.10:
  libyaml-libyaml-perl            0.41-5ubuntu0.14.10.1

Ubuntu 14.04 LTS:
  libyaml-libyaml-perl            0.41-5ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  libyaml-libyaml-perl            0.38-2ubuntu0.2

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