DESCRIPTION:
A vulnerability has been reported in IBM Personal Communications,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error in pcspref.dll
when processing WorkStation profiles and can be exploited to cause a
stack-based buffer overflow via a specially crafted ".ws" file.

Successful exploitation may allow execution of arbitrary code, but
requires tricking a user into opening a malicious file.

The vulnerability is reported in versions 5.9.0 through 5.9.7 and
6.0.0 through 6.0.3.

SOLUTION:
Apply APAR IC81539 or update to version 6.0.4.
