Mandriva Linux Security Advisory : yaml (MDVSA-2015:060)

medium Nessus Plugin ID 81943

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

Updated yaml packages fix security vulnerabilities :

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 (CVE-2013-6393).

Ivan Fratric of the Google Security Team discovered a heap-based buffer overflow vulnerability in LibYAML, a fast YAML 1.1 parser and emitter library. 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 (CVE-2014-2525).

An assertion failure was found in the way the libyaml library parsed wrapped strings. An attacker able to load specially crafted YAML input into an application using libyaml could cause the application to crash (CVE-2014-9130).

Solution

Update the affected lib64yaml-devel and / or lib64yaml0_2 packages.
