Description Eugene Teo (Security Response) 2010-08-18 03:52:29 UTC 
Description of problem:
We leak at least 32bits of kernel memory to user land in tc dump, because we dont init all fields (capab ?) of the dumped structure.

Use C99 initializers so that holes and non explicit fields are zeroed.

Comment 5 Eugene Teo (Security Response) 2010-08-23 07:39:42 UTC 
Statement:

This issue did not affect the version of Linux kernel as shipped with Red Hat
Enterprise Linux 3 as it did not include upstream commit be84c7f6 (history repository) that introduced the problem. A future kernel update in Red Hat Enterprise Linux 4, 5 and Red Hat Enterprise MRG will address this issue.
