-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2013:056 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : libxml2 Date : April 8, 2013 Affected: Business Server 1.0 _______________________________________________________________________ Problem Description: Multiple vulnerabilities was found and corrected in libxml2: A heap-buffer overflow was found in the way libxml2 decoded certain XML entitites. A remote attacker could provide a specially-crafted XML file, which once opened in an application linked against libxml would cause that application to crash, or, potentially, execute arbitrary code with the privileges of the user running the application (CVE-2012-5134). A denial of service flaw was found in the way libxml2 performed string substitutions when entity values for entity references replacement was enabled. A remote attacker could provide a specially-crafted XML file that, when processed by an application linked against libxml2, would lead to excessive CPU consumption (CVE-2013-0338). An Off-by-one error in libxml2 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via unknown vectors (CVE-2011-3102). Multiple integer overflows in libxml2, on 64-bit Linux platforms allow remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors (CVE-2012-2807). The updated packages have been patched to correct these issues. _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-5134 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-0338 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-3102 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-2807 https://bugzilla.redhat.com/show_bug.cgi?id=912400 _______________________________________________________________________ Updated Packages: Mandriva Business Server 1/X86_64: 3b0edbfe45e8b508baec4d44d5f4edaa mbs1/x86_64/lib64xml2_2-2.7.8-14.20120229.2.2.mbs1.x86_64.rpm 9c1fc6692eab2a304b0572baeea9fa3c mbs1/x86_64/lib64xml2-devel-2.7.8-14.20120229.2.2.mbs1.x86_64.rpm b9b4b34210bf9ee8c82e8fa7d9eed44a mbs1/x86_64/libxml2-python-2.7.8-14.20120229.2.2.mbs1.x86_64.rpm c72ca979e12b286151f15a148e21debe mbs1/x86_64/libxml2-utils-2.7.8-14.20120229.2.2.mbs1.x86_64.rpm 9af763be198cbc708a94a8dfff32bb3c mbs1/SRPMS/libxml2-2.7.8-14.20120229.2.2.mbs1.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
