RHEL 4 / 5 / 6 : httpd (RHSA-2011:1245)

high Nessus Plugin ID 56032

Synopsis

The remote Red Hat host is missing a security update for httpd.

Description

The remote Redhat Enterprise Linux 4 / 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:1245 advisory.

The Apache HTTP Server is a popular web server.

A flaw was found in the way the Apache HTTP Server handled Range HTTP headers. A remote attacker could use this flaw to cause httpd to use an excessive amount of memory and CPU time via HTTP requests with a specially-crafted Range header. (CVE-2011-3192)

All httpd users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

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

Note that Nessus has not tested for this issue 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-2011:1245.
