Mandriva Linux Security Advisory : libxml2 (MDVSA-2013:198)
Medium Nessus Plugin ID 69053
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple vulnerabilities has been discovered and corrected in libxml2 :
A denial of service flaw was found in the way libxml2, a library providing support to read, modify and write XML and HTML files, performed string substitutions when entity values for external entity references replacement (--noent option) was requested / enabled during the XML file parsing. A remote attacker could provide a specially crafted XML file containing an external entity expansion, when processed would lead to excessive CPU consumption (denial of service) (CVE-2013-0339). This a different flaw from CVE-2013-0338.
parser.c in libxml2 before 2.9.0, as used in Google Chrome before 28.0.1500.71 and other products, allows remote attackers to cause a denial of service (out-of-bounds read) via a document that ends abruptly, related to the lack of certain checks for the XML_PARSER_EOF state (CVE-2013-2877).
The updated packages have been patched to correct these issues.
SolutionUpdate the affected packages.
