Web services in JRun 4.0 and ColdFusion MX products are vulnerable to a denial of service attack by p
assing incorrectly formed messages
 to the SOAP interfaces exposed by ColdFusion MX and JRun.    Both products use an XML parser (either
 Crimson or Xerces)  that can
 be made to run in an almost infinite loop with this specially form message  -  exhausting CPU resour
ces.

WHAT CUSTOMERS SHOULD DO:


We strongly encourage customers to download and install this patch immediately.
