Thanks Thomas! Here's the full advisory. Advisory: ======================== Updated libyaml packages fix security vulnerabilities: Florian Weimer of the Red Hat Product Security Team discovered a heap-based buffer overflow flaw in LibYAML, a fast YAML 1.1 parser and emitter library. A remote attacker could provide a YAML document with a specially-crafted tag 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 (CVE-2013-6393).
