Mandriva 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.
