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

The vulnerability is caused due to missing input validation in
ebus-3-3-2-7.dll when copying data during unmarshalling of GIOP ORB
encapsulated data. This can be exploited to cause a buffer overflow
by sending specially crafted data to the crystalras.exe service
listening on a random TCP port.

Successful exploitation may allow execution of arbitrary code with
SYSTEM privileges.

The vulnerability is reported in version 2011. Other versions may
also be affected.

SOLUTION:
Apply solution described in SAP note 1662272.
