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 the stable distribution (wheezy), this problem has been fixed in version 0.38-3+deb7u3.

For the upcoming stable distribution (jessie), this problem has been fixed in version 0.41-6.

For the unstable distribution (sid), this problem has been fixed in version 0.41-6.

We recommend that you upgrade your libyaml-libyaml-perl packages.");
