Vulnerability Assessment Summary
DSA-067-1 apache

Detailed Explanation for this Vulnerability Assessment

We have received reports that the `apache' package, as included in
the Debian `stable' distribution, is vulnerable to the `artificially
long slash path directory listing vulnerability' as described on href="http://www.securityfocus.com/vdb/bottom.html?vid=2503">SecurityFocus.

This vulnerability was announced to bugtraq by Dan Harkless.

Quoting the SecurityFocus entry for this vulnerability:

A problem in the package could permit directory indexing, and path
discovery. In a default configuration, Apache enables mod_dir,
mod_autoindex, and mod_negotiation. However, by placing a custom
crafted request to the Apache server consisting of a long path name
created artificially by using numerous slashes, this can cause these
modules to misbehave, making it possible to escape the error page,
and gain a listing of the directory contents.

This vulnerability makes it possible for a malicious remote user
to launch an information gathering attack, which could potentially
result in compromise of the system. Additionally, this vulnerability
affects all releases of Apache previous to 1.3.19.

This problem has been fixed in apache-ssl 1.3.9-13.3 and
apache 1.3.9-14. We recommend that you upgrade your packages
immediately.
Warning: The MD5Sum of the .dsc and .diff.gz file don't match
since they were copied from the stable release afterwards, the
content of the .diff.gz file is the same, though, checked.
