Debian Security Advisory DSA 080-1                       security@debian.org

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.
