DESCRIPTION:
A vulnerability has been discovered in CA Internet Security Suite
Plus, which can be exploited by malicious, local users to gain
escalated privileges.

The vulnerability is caused due to an error in the "KmxSbx.sys"
kernel driver when processing IOCTLs and can be exploited to cause a
buffer overflow via e.g. overly large data buffer (greater than 65535
bytes) sent to the 0x88000080 IOCTL.

Successful exploitation allows execution of arbitrary code in the
kernel.

The vulnerability is confirmed in CA Internet Security Suite Plus
2010 (KmxSbx.sys 6.2.0.23). Other versions may also be affected.

SOLUTION:
Grant access to trusted users only.
