GLSA-200907-02 : ModSecurity: Denial of Service

High Nessus Plugin ID 39596


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200907-02 (ModSecurity: Denial of Service)

Multiple vulnerabilities were discovered in ModSecurity:
Juan Galiana Lara of ISecAuditors discovered a NULL pointer dereference when processing multipart requests without a part header name (CVE-2009-1902).
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).
Impact :

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.
Workaround :

There is no known workaround at this time.


All ModSecurity users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-apache/mod_security-2.5.9'
