Package : apache-perl
Vulnerability : several
Problem-Type : remote, local
Debian-specific: no
CVE Id : CAN-2002-0839 CAN-2002-0840 CAN-2002-0843 CAN-2001-0131 CAN-2002-1233
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.
