Red Hat: 2011:1369-01: httpd: Important Advisory
Summary
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.
