Synopsis :

The remote Mandriva Linux host is missing one or more security

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.
