|
|
Multiple vulnerabilities were discovered in ModSecurity:
|
|
</p>
|
|
<ul>
|
|
<li>Juan Galiana Lara of ISecAuditors discovered a NULL pointer
|
|
dereference when processing multipart requests without a part header
|
|
name (CVE-2009-1902).</li>
|
|
<li>Steve Grubb of Red Hat reported that the
|
|
"PDF XSS protection" feature does not properly handle HTTP requests to
|
|
a PDF file that do not use the GET method (CVE-2009-1903).</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker might send requests containing specially crafted
|
|
multipart data or send certain requests to access a PDF file, possibly
|
|
resulting in a Denial of Service (crash) of the Apache HTTP daemon.
|
|
NOTE: The PDF XSS protection is not enabled by default.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ModSecurity users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-apache/mod_security-2.5.9"</code>
|
|
</resolution>
