Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ModSecurity is a popular web application firewall for the Apache HTTP server. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apache/mod_security < 2.5.9 >=3D 2.5.9 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D 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 =3D=3D=3D=3D=3D=3D 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 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D There is no known workaround at this time. Resolution =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D All ModSecurity users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Dwww-apache/mod_security-2.5.9" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2009-1902 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2009-1902 [ 2 ] CVE-2009-1903 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2009-1903 Availability =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200907-02.xml Concerns? =3D=3D=3D=3D=3D=3D=3D=3D=3D Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
