Problems Fixed in This Release

The following problem was fixed in PC-DCE 5.0.9 (and also in 4.0.17):

1. Fixed the buffer overflow, heap corruption, and double free bugs that were announced in the MIT krb5 Security Advisories SA-2005-002 and SA-2005-003.
   
   
2. Fixed pthread_setprio() to actually change the thread's priority.
   
   A process may have a priority class of Real Time, Idle, Below Normal, Normal, Above Normal, or Highest.
   
   For processes in the Real Time priority class, Entegrity maps the pthreads priority values from PRI_OTHER_MIN (zero) to PRI_OTHER_MAX (15) as listed in the following table.
   
   
   

   Priority	Mapped To
   0 (PRI_OTHER_MIN)	Idle (-8)
   1 through 5	Windows thread priorities -7 through -3
   6	Thread-Priority-Lowest
   7	Thread-Priority-Below-Normal
   8	Thread-Priority-Normal (the default)
   9	Thread-Priority-Above-Normal
   10 through 14	Windows thread priorities 3 through 6
   15 (PRI_OTHER_MAX)	Thread-Priority-Time-Critical

   
   
   
   For processes in the Idle, Below Normal, Normal, Above Normal, and Highest priority classes, Entegrity maps the pthreads priorities as listed in the following table.
   
   
   

   Priority	Mapped To
   0 (PRI_OTHER_MIN) and 1	Thread-Priority-Idle
   2 through 4	Thread-Priority-Lowest
   5 through 7	Thread-Priority-Below-Normal
   8	Thread-Priority-Normal the default)
   9 through 11	Thread-Priority-Above-Normal
   12 through 14	Thread-Priority-Highest
   15	Thread-Priority-Time-Critical

   
   For more details on thread priorities, consult the Microsoft Developers Network (MSDN) documentation.


3. Additional fix for Terminal Server Version: The TS version also includes a bug fix for a policy change introduced by Microsoft in Windows 2000 Server SP4. Microsoft added a new security policy that, by default, prevents users from creating objects in the Windows global namespace. PC-DCE used global file-mapping objects during the creation of CDS per-user caches. PC-DCE now uses local file-mapping objects.

Applying PC-DCE 5.0.9

To upgrade to PC-DCE 5.0.9:

1. Download PC-DCE 5.0.9 . (See "Obtaining PC-DCE 5.0.9" above for download links.) 
     
   
2. Unzip the files and then run Setup. You are given the choice to Modify, Repair, or Remove kits. Choose Repair. Your present installation will be updated to version 5.0.6.
     
   
3. Reboot the machine. The update does not take effect until the machine has been rebooted.

   Note: If you are updating a host running the Security or CDS Server as a replica, it may take a minute or two for the daemons to resynchronize themselves with the master. Initially, the PC-DCE Service Panel may say the daemons are unavailable. After about one minute (or possibly longer for larger cells), click Refresh and the display will show that the servers are running normally.
