[slackware-security] libyaml (SSA:2014-111-01)

New libyaml packages are available for Slackware 13.1, 13.37, 14.0, 14.1,
and -current to fix a security issue.

Here are the details from the Slackware 14.1 ChangeLog:
patches/packages/libyaml-0.1.6-i486-1_slack14.1.txz: Upgraded.
This update fixes a heap overflow in URI escape parsing of YAML in Ruby,
where a specially crafted string could cause a heap overflow leading to
arbitrary code execution.
For more information, see:
(* Security fix *)
