_______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:198 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : libxml2 Date : July 24, 2013 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Multiple 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. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-0339 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-2877 https://bugzilla.redhat.com/show_bug.cgi?id=915149 https://bugzilla.redhat.com/show_bug.cgi?id=983204 http://advisories.mageia.org/MGASA-2013-0218.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 4ad243c16e07e9f6850513c57cd1aa74 mbs1/x86_64/lib64xml2_2-2.7.8-14.20120229.2.3.mbs1.x86_64.rpm 5bae4c7471edb1a4dfe267588b8f9160 mbs1/x86_64/lib64xml2-devel-2.7.8-14.20120229.2.3.mbs1.x86_64.rpm 6800af0e5ca73cccc48bf35596e57ee0 mbs1/x86_64/libxml2-python-2.7.8-14.20120229.2.3.mbs1.x86_64.rpm 8af9449c2a438abccd86ff5d044b2e71 mbs1/x86_64/libxml2-utils-2.7.8-14.20120229.2.3.mbs1.x86_64.rpm 956fd0fbd8ccd0a705747ea469b87ff7 mbs1/SRPMS/libxml2-2.7.8-14.20120229.2.3.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
