Synopsis ========
Apache can be exploited for cross-site scripting attacks and is vulnerable to a Denial of Service attack.
Background ==========
The Apache HTTP server is one of the most popular web servers on the Internet. mod_imap provides support for server-side image maps; mod_ssl provides secure HTTP connections.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-www/apache < 2.0.55-r1 >= 2.0.55-r1 *>= 2.0.54-r16 == 1.3.34-r2 *>= 1.3.34-r11
Description ===========
Apache's mod_imap fails to properly sanitize the "Referer" directive of imagemaps in some cases, leaving the HTTP Referer header unescaped. A flaw in mod_ssl can lead to a NULL pointer dereference if the site uses a custom "Error 400" document. These vulnerabilities were reported by Marc Cox and Hartmut Keil, respectively.
Impact ======
A remote attacker could exploit mod_imap to inject arbitrary HTML or JavaScript into a user's browser to gather sensitive information. Attackers could also cause a Denial of Service on hosts using the SSL module (Apache 2.0.x only).
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Apache users should upgrade to the latest version, depending on whether they still use the old configuration style (/etc/apache/conf/*.conf) or the new one (/etc/apache2/httpd.conf).
2.0.x users, new style config:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-www/apache-2.0.55-r1"
2.0.x users, old style config:
# emerge --sync # emerge --ask --oneshot --verbose "=net-www/apache-2.0.54-r16"
1.x users, new style config:
# emerge --sync # emerge --ask --oneshot --verbose "=net-www/apache-1.3.34-r11"
1.x users, old style config:
# emerge --sync # emerge --ask --oneshot --verbose "=net-www/apache-1.3.34-r2"
