Package        : libyaml
CVE ID         : CVE-2014-9130
Debian Bug     : 771366

Jonathan Gray and Stanislaw Pitucha found an assertion failure in the
way wrapped strings are parsed in LibYAML, a fast YAML 1.1 parser and
emitter library. An attacker able to load specially crafted YAML input
into an application using libyaml could cause the application to crash.

For the stable distribution (wheezy), this problem has been fixed in
version 0.1.4-2+deb7u5.

For the upcoming stable distribution (jessie), this problem has been
fixed in version 0.1.6-3.

For the unstable distribution (sid), this problem has been fixed in
version 0.1.6-3.

We recommend that you upgrade your libyaml packages.

CVE ID         : CVE-2014-9130
Debian Bug     : 771365

way wrapped strings are parsed in LibYAML, a fast YAML 1.1 parser and
emitter library. An attacker able to load specially crafted YAML input
into an application using libyaml could cause the application to crash.

This update corrects this flaw in the copy that is embedded in the
libyaml-libyaml-perl package.

For the stable distribution (wheezy), this problem has been fixed in
version 0.38-3+deb7u3.

For the upcoming stable distribution (jessie), this problem has been
fixed in version 0.41-6.

For the unstable distribution (sid), this problem has been fixed in
version 0.41-6.

We recommend that you upgrade your libyaml-libyaml-perl packages.
