3. Description:
libxml2 is a library for parsing and manipulating XML files. It includes
support for reading, modifying, and writing XML and HTML files.
An integer overflow flaw causing a heap-based buffer overflow was found in
the libxml2 XML parser. If an application linked against libxml2 processed
untrusted, malformed XML content, it could cause the application to crash
or, possibly, execute arbitrary code. (CVE-2008-4226)
A denial of service flaw was discovered in the libxml2 XML parser. If an
application linked against libxml2 processed untrusted, malformed XML
content, it could cause the application to enter an infinite loop.
(CVE-2008-4225)

1. Summary:
Updated libxml2 packages that fix several security issues are now available
for Red Hat Enterprise Linux 4.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

3. Description:
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)
A flaw 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.
(CVE-2011-2834)
Note: Red Hat does not ship any applications that use libxml2 in a way that
would allow the CVE-2011-2834 flaw to be exploited; however, third-party
applications may allow XPath expressions to be passed which could trigger
this flaw.
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)
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.

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
