Package        : libyaml
Vulnerability  : regression
Debian Bug     : 738587

The security update released in DSA-2850-1 for libyaml introduced a
regression in libyaml failing to parse a subset of valid yaml documents.
For reference the original advisory text follows.

Florian Weimer of the Red Hat Product Security Team discovered a
heap-based buffer overflow flaw in LibYAML, a fast YAML 1.1 parser and
emitter library. A remote attacker could provide a YAML document with a
specially-crafted tag 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.

For the oldstable distribution (squeeze), this problem has been fixed in
version 0.1.3-1+deb6u3.

For the stable distribution (wheezy), this problem has been fixed in
version 0.1.4-2+deb7u3.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your libyaml packages.
