DESCRIPTION:
A vulnerability has been reported in Jenkins, 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 in the Winstone servlet container 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 versions 1.446 and prior and
versions 1.424.1 and prior.
SOLUTION:
Update to version 1.447 or 1.424.2 (please see the vendor's advisory
for more information).
PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
