Multiple vulnerabilities have been discovered in Apache.
|Package||www-servers/apache on all architectures|
|Affected versions||< 2.2.8|
|Unaffected versions||>= 2.2.8|
The Apache HTTP server is one of the most popular web servers on the Internet.
Adrian Pastor and Amir Azam (ProCheckUp) reported that the HTTP Method specifier header is not properly sanitized when the HTTP return code is "413 Request Entity too large" (CVE-2007-6203). The mod_proxy_balancer module does not properly check the balancer name before using it (CVE-2007-6422). The mod_proxy_ftp does not define a charset in its answers (CVE-2008-0005). Stefano Di Paola (Minded Security) reported that filenames are not properly sanitized within the mod_negotiation module (CVE-2008-0455, CVE-2008-0456).
A remote attacker could entice a user to visit a malicious URL or send specially crafted HTTP requests (i.e using Adobe Flash) to perform Cross-Site Scripting and HTTP response splitting attacks, or conduct a Denial of Service attack on the vulnerable web server.
There is no known workaround at this time.
All Apache users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.8"
