libyaml security update

CentOS Errata and Security Advisory CESA-2015:0100

YAML is a data serialization format designed for human readability and
interaction with scripting languages. 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.
(CVE-2014-9130)

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.
