Problems Fixed in This Release

The following problems were fixed in PC-DCE 5.0.9 (also in 4.0.17 and 5.1.5):

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.

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.
