Package        : htdig
Vulnerability  : unauthorized gathering of data
Problem-Type   : remote DoS, local information retrieval
Debian-specific: no

Nergal reported a vulnerability in the htsearch program which is
distributed as part of the ht://Dig package, a indexing and searching
system for small domains or intranets.  Using former versions it was
able to pass the parameter `-c' to the cgi program in order to use a
different configuration file.

A malicious user could point htsearch to a file like `/dev/zero' and
let the server run in an endless loop, trying to read config
parameters.  If the user has write permission on the server he can
point the program to it and retrive any file readable by the webserver
user id.

This problem has been fixed in version of 3.1.5-2.1 for Debian
GNU/Linux 2.2.

We recommend that you upgrade your htdig package immediately.

wget url
	will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
