4a661c45126cb28fec4cfaca3ea442365ce97bcf38318f65b028a97746e2ef46Mandriva Linux Security Advisory 2013-056 - A heap-buffer overflow was found in the way libxml2 decoded certain XML entities. 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. 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. An Off-by-one error in libxml2 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors. 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. The updated packages have been patched to correct these issues.

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. The updated packages have been upgraded to the 2.7.6 version and patched to correct this issue.
34b284fe798b5b0d153a18991515bc5539739d12335991c5a256cbe3ca760674Red Hat Security Advisory 2013-0581-01 - The libxml2 library is a development toolbox providing the implementation of various XML standards. 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. All users of libxml2 are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The desktop must be restarted for this update to take effect.
