According to David Wagner, iDEFENSE and the Apache HTTP Server Project, several vulnerabilities have been found in the Apache package, a commonly used webserver. Most of the code is shared between the Apache and Apache-SSL 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 scripting attack, or steal cookies from other web site users. Vulnerabilities in the included legacy programs htdigest, htpasswd and ApacheBench can be exploited when called via CGI. Additionally the insecure temporary file creation in htdigest and htpasswd can also be exploited locally.
The Common Vulnerabilities and Exposures (CVE) project identified the following vulnerabilities :
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.
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.
CAN-2002-0843: There were some possible overflows in the utility ApacheBench (ab) which could be exploited by a malicious server.
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. (binaries not included in apache-ssl package though)
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.
This is the same vulnerability as CAN-2002-1233, which was fixed in potato already but got lost later and was never applied upstream. (binaries not included in apache-ssl package though)
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. (binary not included in apache-ssl package though) These problems have been fixed in version 1.3.26.1+1.48-0woody3 for the current stable distribution (woody) and in 1.3.9.13-4.2 for the old stable distribution (potato). Corrected packages for the unstable distribution (sid) are expected soon.
