DSA 195-1-New Apache-Perl packages fix several vulnerabilities

by Nikola Strahija on November 13th, 2002 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.
