"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 :

  - 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.

  - 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.

  - 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."
