Package         : apache,apache-ssl
Problem type    : remote exploit
Debian-specific : no

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

This vulnerability was announced to bugtraq by Dan Harkless.

Quoting the SecurityFocus entry for this vulnerability:

 A problem in the package could allow 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.
