<p>libxml2 is the XML C parser and toolkit developed for the Gnome project.</p>

<description>
|
|
<p>The "xmlStringLenDecodeEntities()" function in parser.c contains a
|
|
boundary error which could possibly cause a heap-based buffer overflow.

<impact type="normal">
|
|
<p>A remote attacker could entice a user to open a specially crafted XML
|
|
file in an application linked against libxml2, possibly resulting in the
|
|
remote execution of arbitrary code with the permissions of the user
|
|
running the application, or Denial of Service.

|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All libxml2 users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.7.8-r4"
|
|
</code>
|
|
|
|
<p>Packages which depend on this library may need to be recompiled. Tools
|
|
such as revdep-rebuild may assist in identifying some of these packages.
