Synopsis ========
Two vulnerabilities in ModSecurity might lead to a Denial of Service.
Background ==========
ModSecurity is a popular web application firewall for the Apache HTTP server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apache/mod_security < 2.5.9 >=3D 2.5.9
Description ===========
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.
Resolution ==========
All ModSecurity users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=3Dwww-apache/mod_security-2.5.9"
