Package        : libapreq2-perl
Vulnerability  : design error
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2006-0042
BugTraq ID     : 16710
Debian Bug     : 354060 358689

Gunnar Wolf noticed that the correction for the following problem was
not complete and requires an update.  For completeness we're
providing the original problem description:

   An algorithm weakness has been discovered in Apache2::Request, the
   generic request library for Apache2 which can be exploited remotely
   and cause a denial of service via CPU consumption.

The old stable distribution (woody) does not contain this package.

For the stable distribution (sarge) this problem has been fixed in
version 2.04-dev-1sarge2.

For the unstable distribution (sid) this problem has been fixed in
version 2.07-1.

We recommend that you upgrade your libapreq2, libapache2-mod-apreq2
and libapache2-request-perl packages.

        will fetch the file for you
