Mandriva Linux Security Advisory : libxml2 (MDVSA-2015:111)

Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

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).
