DESCRIPTION:
A vulnerability has been reported in Apache APR, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error within a hash generation
function when hashing form posts and updating a hash table. This can
be exploited to cause a hash collision resulting in high CPU
consumption via a specially crafted form sent in a HTTP POST
request.

The vulnerability is reported in version 1.4.5. Other versions may
also be affected.

SOLUTION:
Currently there is no known workaround.

PROVIDED AND/OR DISCOVERED BY:
