Mandriva Linux Security Advisory : yaml (MDVSA-2014:034)

medium Nessus Plugin ID 72532

Language:

Synopsis

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

Description

A vulnerability has been discovered and corrected in yaml :

The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before 0.1.5 performs an incorrect cast, which allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted tags in a YAML document, which triggers a heap-based buffer overflow (CVE-2013-6393).

The updated packages have been upgraded to the 0.1.5 version which is not vulnerable to this issue.

Solution

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