Debian DSA-067-1 : apache - Remote exploit

medium Nessus Plugin ID 14904

Synopsis

The remote Debian host is missing a security-related update.

Description

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 SecurityFocus.

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.

Solution

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.
