Bug description:
  https://bugzilla.redhat.com/show_bug.cgi?id=1033990

  "A heap-based buffer overflow flaw was found in the way libyaml parsed
  YAML tags. 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."

  Fixed in Debian package 0.1.4-2+deb7u2

  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737076

  That fix has been merged into Trusty already (0.1.4-3ubuntu1) but no
  others.
