USN-2461-2: libyaml-libyaml-perl vulnerability

12 January 2015

Applications using libyaml-libyaml-perl could be made to crash if they received specially crafted input.




Stanisław Pitucha and Jonathan Gray discovered that
libyaml-libyaml-perl did not properly handle wrapped strings. An
attacker could create specially crafted YAML data to trigger an assert,
causing a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04

After a standard system update you need to restart applications using
libyaml-libyaml-perl to make all the necessary changes.
