Mandriva Linux Security Advisory : yaml (MDVSA-2014:034)
Medium Nessus Plugin ID 72532
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA 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.
SolutionUpdate the affected lib64yaml-devel and / or lib64yaml0_2 packages.
