DESCRIPTION:
A weakness has been reported in Comodo Internet Security, which can
be exploited by malicious, local users to bypass certain security
features.

The weakness is caused due to the application not properly
implementing security checks in certain kernel hooks, which can be
exploited to bypass those checks by changing the arguments after the
check but prior to their use by the system call.

SOLUTION:
Update to version 4.1.149672.916.
