    Posted ByLinuxSecurity Advisories
    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.

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