DESCRIPTION:
Debian has issued an update for libapache2-mod-rpaf. This fixes a
vulnerability, which can be exploited by malicious people to cause a
DoS (Denial of Service) in an application using the module.

The vulnerability is caused due to an error when processing certain
"X-Forward-For" HTTP headers and can be exploited to cause a
segmentation fault in an application using the module via a HTTP
request containing a specially crafted "X-Forward-For" header.

SOLUTION:
Apply updated packages via the apt-get package manager.
