To learn about these new issues and what actions you can take to address them, please visit the Security Zone at the Macromedia website: http://www.macromedia.com/security ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ MSPB02-14 - Patch available for web services denial-of-service vulnerability in JRun 4.0 and ColdFusion MX. Originally Posted: December 11, 2002 ~~~~~~~ SUMMARY Web services in JRun 4.0 and ColdFusion MX products are vulnerable to a denial of service attack by passing 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 resources. ~~~~~~~ WHAT CUSTOMERS SHOULD DO: We strongly encourage customers to download and install this patch immediately. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reporting Security Issues ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Macromedia is committed to addressing security issues and providing customers with the information on how they can protect themselves.
