Mandriva Linux Security Advisory MDVSA-2014:034
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : yaml
Date : February 14, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem 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.
