Synopsis
Multiple vulnerabilities in Apache might lead to a Denial of Service.
2.
Impact Information
Background
The Apache HTTP server is one of the most popular web servers on the
Internet.
Description
Multiple vulnerabilities have been discovered in Apache:
-
Dustin Kirkland reported that the mod_ssl module can leak memory when
the client reports support for a compression algorithm (CVE-2008-1678).
-
Ryujiro Shibuya reported that the ap_proxy_http_process_response()
function in the mod_proxy module does not limit the number of forwarded
interim responses (CVE-2008-2364).
-
sp3x of SecurityReason reported a Cross-Site Request Forgery
vulnerability in the balancer-manager in the mod_proxy_balancer module
(CVE-2007-6420).
Impact
A remote attacker could exploit these vulnerabilities by connecting to
an Apache httpd, by causing an Apache proxy server to connect to a
malicious server, or by enticing a balancer administrator to connect to
a specially-crafted URL, resulting in a Denial of Service of the Apache
daemon.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All Apache users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/apache-2.2.9"
|
