Mandriva Linux Security Advisory MDVSA-2015:111
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libxml2
Date : March 29, 2015
Affected: Business Server 2.0
_______________________________________________________________________

Problem Description:

Updated libxml2 packages fix security vulnerabilities:

It was discovered that libxml2, a library providing support to
read, modify and write XML files, incorrectly performs entity
substituton in the doctype prolog, even if the application using
libxml2 disabled any entity substitution. A remote attacker could
provide a specially-crafted XML file that, when processed, would lead
to the exhaustion of CPU and memory resources or file descriptors
(CVE-2014-0191).

A denial of service flaw was found in libxml2, a library providing
support to read, modify and write XML and HTML files. A remote attacker
could provide a specially crafted XML file that, when processed by
an application using libxml2, would lead to excessive CPU consumption
(denial of service) based on excessive entity substitutions, even if
entity substitution was disabled, which is the parser default behavior
(CVE-2014-3660).
