CVE-2013-6393: Buffer Overflow

First published: Mon Nov 25 2013(Updated: )

A heap-based buffer overflow flaw was found in the way libyaml parsed YAML tags. 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. Acknowledgements: This issue was discovered by Florian Weimer of the Red Hat Product Security Team.
