Description Eugene Teo (Security Response) 2010-09-22 03:58:39 UTC 
Description of problem:
While reviewing commit 1c40be12f7d8ca1d387510d39787b12e512a7ce8 (CVE-2010-2942), Jeff Mahoney audited other users of tc_action_ops->dump for information leaks.

That commit covered almost all of them but act_police still had a leak.

opt.limit and opt.capab aren't zeroed out before the structure is passed out.
