vulnerability :

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
(CVE-2014-9130).

The perl-YAML-LibYAML package is also affected, as it was derived from
the same code. Both have been patched to fix this issue."
