Affected versions
MBS1 x86_64

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.
