Insight
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. CVE-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. CVE-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. CVE-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. CVE-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. CVE-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.
