Description Vincent Danen 2011-01-05 00:03:50 UTC
Emmanuel Bouillon reported a double-free flaw in scsi-target-utils that could cause the tgtd daemon to crash with memory corruption on receipt of certain network traffic, leading to a denial of service condition.


Red Hat would like to thank Emmanuel Bouillon of NATO C3 Agency for reporting this issue.

I can confirm this patch fixes the problem.

Comment 6 Barry Donahue 2011-01-24 19:10:29 UTC
Verified for async errata.

Comment 7 Josh Bressers 2011-03-01 15:04:31 UTC
Did this fix ever make it upstream? My records show it's still embargoed.

Comment 8 fujita.tomonori 2011-03-04 01:38:35 UTC
Can I merge this fix into the public tree? I've been waiting for someone at RedHat to let me know the day when I can make this public.

Comment 9 Vincent Danen 2011-03-04 02:12:49 UTC
An unembargo date was never negotiated as far as I can recall.  Perhaps we could set a date for next week, perhaps Wednesday or Thursday (the 9th or 10th)?

Comment 10 fujita.tomonori 2011-03-04 02:18:16 UTC
Either is fine by me

Comment 11 manu 2011-03-05 17:08:39 UTC
Dear all,
If you ever happen to include an acknowledgement, please also mention my employer: NATO C3 Agency.

Thank you for that, we will certainly do so.

In terms of disclosure, let's make it for this coming Wednesday (March 9th) at 14:00 EST.  Does that sound good?

Comment 13 fujita.tomonori 2011-03-07 23:32:49 UTC
Sounds good to me. I'll merge the fix into the public git tree after the time.

Comment 14 Vincent Danen 2011-03-08 15:37:29 UTC
Perfect.  Thank you!

Comment 15 Vincent Danen 2011-03-09 18:22:50 UTC
This is now public, so upstream merges can take place any time now:
