+ <background>
+ <p>
+ ModSecurity is a popular web application firewall for the Apache HTTP
+ server.
+ </p>
+ </background>
+ <description>
+ <p>
+ 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 "&gt;=www-apache/mod_security-2.5.9"</code>
+ </resolution>
