tag_insight = "The libxml2 library is a development toolbox providing the implementation
of various XML standards. One of those standards is the XML Path Language
(XPath), which is a language for addressing parts of an XML document.
A heap-based buffer overflow flaw was found in the way libxml2 decoded
entity references with long names. A remote attacker could provide a
specially-crafted XML file that, when opened in an application linked
against libxml2, would cause the application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2011-3919)
An off-by-one error, leading to a heap-based buffer overflow, was found in
the way libxml2 parsed certain XML files. A remote attacker could provide a
specially-crafted XML file that, when opened in an application linked
against libxml2, would cause the application to crash or, potentially,
execute arbitrary code with the privileges of the user running the
application. (CVE-2011-0216)
An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way libxml2 parsed certain XPath expressions. If an attacker
were able to supply a specially-crafted XML file to an application using
libxml2, as well as an XPath expression for that application to run against
the crafted file, it could cause the application to crash or, possibly,
execute arbitrary code. (CVE-2011-1944)
Flaws were found in the way libxml2 parsed certain XPath expressions. If an
attacker were able to supply a specially-crafted XML file to an application
using libxml2, as well as an XPath expression for that application to run
against the crafted file, it could cause the application to crash.
(CVE-2010-4008, CVE-2011-2834)
An out-of-bounds memory read flaw was found in libxml2. A remote attacker
could provide a specially-crafted XML file that, when opened in an
application linked against libxml2, would cause the application to crash.
(CVE-2011-3905)
Note: Red Hat does not ship any applications that use libxml2 in a way that
would allow the CVE-2011-1944, CVE-2010-4008, and CVE-2011-2834 flaws to be
exploited; however, third-party applications may allow XPath expressions to
be passed which could trigger these flaws.
Red Hat would like to thank the Google Security Team for reporting the
CVE-2010-4008 issue. Upstream acknowledges Bui Quang Minh from Bkis as the
original reporter of CVE-2010-4008.
All users of libxml2 are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. The desktop must
be restarted (log out, then log back in) for this update to take effect.";
