Sebastien Bocahu discovered that the reverse proxy add forward module for the Apache webserver is vulnerable to a denial of service attack through a single crafted request with many headers.

For the stable distribution (squeeze), this problem has been fixed in version 0.5-3+squeeze1. For the testing distribution (wheezy) and unstable distribution (sid), this problem has been fixed in version 0.6-1. We recommend that you upgrade your libapache2-mod-rpaf packages.

rpaf is short for reverse proxy add forward.
