Mandriva Linux Security Advisory 2015-060 - 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. 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. An assertion failure was found in the way the libyaml library parsed wrapped strings. An attacker able to load specially crafted YAML input into an application using libyaml could cause the application to crash.

LibYAML is a YAML parser and emitter written in C. An assertion failure was found in the way the libyaml library parsed wrapped strings. An attacker able to load specially crafted YAML input into an application using libyaml could cause the application to crash. All libyaml users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications linked against the libyaml library must be restarted for this update to take effect.
