Name : perl-YAML-LibYAML
Product : Fedora 21
Version : 0.54
Release : 1.fc21
URL : http://search.cpan.org/dist/YAML-LibYAML/
Summary : Perl YAML Serialization using XS and libyaml
Description :
Kirill Siminov’s “libyaml” is arguably the best YAML implementation. The C
library is written precisely to the YAML 1.1 specification. It was originally
bound to Python and was later bound to Ruby.

Update Information:

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.
