Security database references:

In Mitre's CVE dictionary: CVE-2014-2525.
More information:

Ivan Fratric of the Google Security Team discovered a heap-based buffer overflow vulnerability in LibYAML, a fast YAML 1.1 parser and emitter library. A remote attacker could provide a specially-crafted YAML document that, when parsed by an application using libyaml, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

For the oldstable distribution (squeeze), this problem has been fixed in version 0.1.3-1+deb6u4.

For the stable distribution (wheezy), this problem has been fixed in version 0.1.4-2+deb7u4.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your libyaml packages.
