Releases

• Ubuntu 14.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• libyaml-libyaml-perl - Perl interface to libyaml, a YAML implementation

Details

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.

Ubuntu 14.10

• libyaml-libyaml-perl - 0.41-5ubuntu0.14.10.1
