    These vulnerabilities could allow an attacker to enact a denial of service against a server or execute a cross site scripting attack, or steal cookies from other web site users.

    BugTraq ID     : 5847 5884 5887
    
    According to David Wagner, iDEFENSE and the Apache HTTP Server
    Project, several vulnerabilities have been found in the Apache server
    package, a commonly used webserver.  Most of the code is shared
    between the Apache and Apache-Perl packages, so vulnerabilities are
    shared as well.
    
    These vulnerabilities could allow an attacker to enact a denial of
    service against a server or execute a cross site scripting attack, or
    steal cookies from other web site users.  The Common Vulnerabilities
    and Exposures (CVE) project identified the following vulnerabilities:
    
    1. CAN-2002-0839: A vulnerability exists on platforms using System V
       shared memory based scoreboards.  This vulnerability allows an
       attacker to execute code under the Apache UID to exploit the Apache
       shared memory scoreboard format and send a signal to any process as
       root or cause a local denial of service attack.
    
    2. CAN-2002-0840: Apache is susceptible to a cross site scripting
       vulnerability in the default 404 page of any web server hosted on a
       domain that allows wildcard DNS lookups.
    
    3. CAN-2002-0843: There were some possible overflows in the utility
       ApacheBench (ab) which could be exploited by a malicious server.
       No such binary programs are distributed by the Apache-Perl package,
       though.
    
    4. CAN-2002-1233: A race condition in the htpasswd and htdigest
       program enables a malicious local user to read or even modify the
       contents of a password file or easily create and overwrite files as
       the user running the htpasswd (or htdigest respectively) program.
       No such binary programs are distributed by the Apache-Perl package,
       though.
    
    5. CAN-2001-0131: htpasswd and htdigest in Apache 2.0a9, 1.3.14, and
       others allows local users to overwrite arbitrary files via a
       symlink attack.  No such binary programs are distributed by the
       Apache-Perl package, though.
    
    6. NO-CAN: Several buffer overflows have been found in the ApacheBench
       (ab) utility that could be exploited by a remote server returning
       very long strings.  No such binary programs are distributed by the
       Apache-Perl package, though.
    
    These problems have been fixed in version 1.3.26-1-1.26-0woody2 for
    the current stable distribution (woody), in
    1.3.9-14.1-1.21.20000309-1.1 for the old stable distribution (potato)
    and in version 1.3.26-1.1-1.27-3-1 for the unstable distribution
    (sid).
    
    We recommend that you upgrade your Apache-Perl 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.
