A buffer "over-read" flaw was found in Apache httpd used for caching. This
allows a malicious origin server to possibly cause a process crash on a caching
forward proxy, which is a DoS for a threaded MPM on httpd 2.0+
On httpd 1.3 this would cause a client crash but this is not considered a
security issue as httpd would continue to run and spawn new children as required.
This issue has been addressed in following products:
Red Hat Certificate System 7.3
