libyaml-libyaml-perl - security update

Jonathan Gray and Stanislaw Pitucha found an assertion failure in the
way wrapped strings are parsed in LibYAML, a fast YAML 1.1 parser and
emitter library. An attacker able to load specially crafted YAML input
into an application using libyaml could cause the application to crash.

This update corrects this flaw in the copy that is embedded in the
libyaml-libyaml-perl package.

For Debian 6 Squeeze, these issues have been fixed in libyaml-libyaml-perl version 0.33-1+squeeze4
