DESCRIPTION:
Some vulnerabilities have been reported in ZomeAlarm products, which
can be exploited by malicious, local users to gain escalated
privileges.

Insufficient address space verification within the 0x22208F and
0x0x2220CF IOCTL handlers of SRESCAN.SYS and insecure permissions on
the \\.\SreScan DOS device interface can be exploited to e.g. access
the said IOCTL handlers and overwrite arbitrary memory and execute
code with kernel privileges.

The vulnerabilities are reported in SRESCAN.SYS version 5.0.63.0
included in the free version of ZoneAlarm. Other versions may also be
affected.

SOLUTION:
Update to version 5.0.156.0 or higher of the ZoneAlarm Spyware
Removal Engine (current deployed version is 5.0.162.0).
