RHEL 4 : httpd (RHSA-2005:608)

high Nessus Plugin ID 19673

Synopsis

The remote Red Hat host is missing one or more security updates for httpd.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2005:608 advisory.

The Apache HTTP Server is a popular and freely-available Web server.

A flaw was discovered in mod_ssl's handling of the SSLVerifyClient directive. This flaw occurs if a virtual host is configured using SSLVerifyClient optional and a directive SSLVerifyClient required is set for a specific location. For servers configured in this fashion, an attacker may be able to access resources that should otherwise be protected, by not supplying a client certificate when connecting. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-2700 to this issue.

A flaw was discovered in Apache httpd where the byterange filter would buffer certain responses into memory. If a server has a dynamic resource such as a CGI script or PHP script that generates a large amount of data, an attacker could send carefully crafted requests in order to consume resources, potentially leading to a Denial of Service. (CAN-2005-2728)

Users of Apache httpd should update to these errata packages that contain backported patches to correct these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL httpd package based on the guidance in RHSA-2005:608.
