Mandriva Linux Security Advisory MDVSA-2014:069
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : perl-YAML-LibYAML
Date : April 9, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated perl-YAML-LibYAML 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).

The perl-YAML-LibYAML package is being updated as it contains an
embedded copy of LibYAML.
