libyaml-libyaml-perl vulnerabilities
==========================================================================

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

- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

libyaml-libyaml-perl could be made to crash or run programs if it opened a
specially crafted YAML file.

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

Details:

Florian Weimer discovered that libyaml-libyaml-perl incorrectly handled
certain large YAML documents. An attacker could use this issue to cause
libyaml-libyaml-perl to crash, resulting in a denial of service, or
possibly execute arbitrary code. (CVE-2013-6393)

Ivan Fratric discovered that libyaml-libyaml-perl incorrectly handled
certain malformed YAML documents. An attacker could use this issue to cause
libyaml-libyaml-perl to crash, resulting in a denial of service, or
possibly execute arbitrary code. (CVE-2014-2525)

Update instructions:

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

Ubuntu 13.10:
libyaml-libyaml-perl 0.38-3ubuntu0.13.10.1

Ubuntu 12.10:
libyaml-libyaml-perl 0.38-3ubuntu0.12.10.1

Ubuntu 12.04 LTS:
