DB2 Version 9.5 Fix Pack 10 for Linux, UNIX, and Windows

APAR status

• Closed as program error.

Error description

• There is a security vulnerability in the DB2 Administration
  Server (DAS) which a malicious user can remotely
  exploit to gain elevated privilege or to cause a denial of
  service.
  
  This vulnerability does not apply to DAS running on the
  Windows platforms.
  
  This problem was reported to IBM by an anonymous researcher
  working with the iDefense Vulnerability Contributor Program
  (VCP).
  

Local fix

• DB2 installs DAS by default. However, DAS is only required for
  using the Control Center tools or performing remote
  administration.  If you do not use these features then do not
  enable DAS.
