3. Description:
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.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259
