Insight

Insight

According to David Wagner, iDEFENSE and the Apache HTTP Server Project, several remotely exploitable vulnerabilities have been found in the Apache package, a commonly used webserver. These vulnerabilities could allow an attacker to enact a denial of service against a server or execute a cross scripting attack. 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 who can execute 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. 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. 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. This is the same vulnerability as CVE-2002-1233, which was fixed in potato already but got lost later and was never applied upstream. 5. 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. These problems have been fixed in version 1.3.26-0woody3 for the current stable distribution (woody) and in 1.3.9-14.3 for the old stable distribution (potato). Corrected packages for the unstable distribution (sid) are expected soon. We recommend that you upgrade your Apache package immediately.
