The following vulnerabilities were reported after a test with the
|
|
Codenomicon XML fuzzing framework:
|
|
</p>
|
|
<ul>
|
|
<li>
|
|
Two use-after-free vulnerabilities are possible when parsing a XML file
|
|
with Notation or Enumeration attribute types (CVE-2009-2416).
|
|
</li>
|
|
<li>
|
|
A stack consumption vulnerability can be triggered via a large depth of
|
|
element declarations in a DTD, related to a function recursion
|
|
(CVE-2009-2414).
|
|
</li>
|
|
</ul>
|

|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user or automated system to open a
|
|
specially crafted XML document with an application using libxml2
|
|
resulting in a Denial of Service condition.
|
|
</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/libxml2-2.7.3-r2"</code>
|
|
<p>
|
|
NOTE: This is a legacy GLSA. Updates for all affected architectures are
|
|
available since August 30, 2009. It is likely that your system is
|
|
already no longer affected by this issue.
