Description Robert Scheck 2004-06-17 07:07:41 EDT
Description of problem:
In the i2c driver, there is an integer overflow vulnerability during 
the allocation of memory, potentially opening any systems using the 
i2c driver up to a security hole.

The integer overflow problem becomes present when allocating memory, 
which is allowed to occur because of a lack of sanity checks.

For more information have a look to:

Version-Release number of selected component (if applicable):
kernel-2.4.22-1.2188.nptl
kernel-2.4.22-1.2193.nptl

Expected results:
Fix, maybe the attached one or something better.
