Synopsis


Multiple vulnerabilities have been discovered in Apache.


Background


The Apache HTTP server is one of the most popular web servers on the
Internet.


Affected Packages

Package: www-servers/apache
Vulnerable: < 2.2.8
Unaffected: >= 2.2.8
Architectures: All supported architectures


Description


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).


Impact


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.


Workaround


There is no known workaround at this time.


Resolution


All Apache users should upgrade to the latest version:
