Synopsis :

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

Description :

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.
