Issue Overview:

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.

Affected Packages:

httpd

Issue Correction:
Run yum update httpd to update your system.

New Packages:

i686:  
    httpd-devel-2.2.21-1.18.amzn1.i686
