DESCRIPTION:
A weakness has been reported in Qt, which can be exploited by
malicious, local users to bypass certain security restrictions.

The weakness is caused due to the Qt library creating shared memory
blocks with world-readable and world-writable permissions, which can
be exploited to overwrite arbitrary data in the shared memory or read
arbitrary data from the memory.

The weakness is reported in versions 4.4.0 through 5.0.0.

SOLUTION:
Apply patches if available.
