Description Vincent Danen 2011-01-31 18:04:37 UTC
Two vulnerabilities were reported [1],[2] in gypsy, a GPS multiplexing daemon.

The first is that it reads arbitrary files as the root user on behalf of a regular user (CVE-2011-0523).  The second is that there is a buffer overflow in nmea device input handling which could potentially lead to privilege escalation (CVE-2011-0524).  Both issues have been reported upstream [3], however there has been no response (the Ubuntu bug indicates upstream was noticed 20101214 with no response.  There is also a SUSE bug [4] with some further information.

Comment 1 Vincent Danen 2011-01-31 18:08:01 UTC
It also looks as though this software may be abandoned.  There is no upstream activity since June 2010: http://cgit.freedesktop.org/gypsy/

Comment 2 Vincent Danen 2011-01-31 18:08:38 UTC
Created gypsy tracking bugs for this issue

Affects: fedora-all [bug 674131]

Comment 3 Peter Robinson 2011-01-31 18:13:18 UTC
Upstream isn't abandoned but there's not a lot of churn. I'll poke upstream directly to get a response.

Comment 4 Vincent Danen 2011-01-31 18:30:52 UTC
Many thanks for that, Peter.

Comment 5 Josh Bressers 2011-04-07 19:33:53 UTC
Hi Peter,

Any update on this from upstream?

Comment 6 Peter Robinson 2011-04-08 08:20:31 UTC
I reported it on the meego bugzilla as I'd not got any response from the maintainers. https://bugs.meego.com/show_bug.cgi?id=14396

It seems there's a patch been added (only just saw it) but I'm not able to make a judgement on whether it fixes the problem. Quite happy to patch and push it in Fedora if someone can review and ACK it.

Comment 7 Vincent Danen 2011-04-28 21:31:58 UTC
Peter, can you attach the patch to this bug?  I tried to load up that bug and don't have an account there (so I suspect I won't have privileges if I go ahead and make one).  You can make the attachment private (or email it to me directly perhaps).


Comment 8 Peter Robinson 2011-04-28 22:26:51 UTC
I've emailed it as I couldn't see how to set the attachment as private, only the entire bug.

Comment 10 Vincent Danen 2011-04-28 23:35:37 UTC
Thanks, Peter.  I've got it.  I think that patch should be ok; might be nice to get it into Fedora and test it out if nothing else.  The patch only addresses CVE-2011-0523 (the first issue) from what I can tell, and not the buffer overflow in nmea device handling.  Has that been discussed upstream at all?

I still see no activity in the upstream git -- do we know if this patch will land there?

Comment 12 Bastien Nocera 2011-10-12 11:21:02 UTC
Waiting on upstream to review the patches:

Feel free to comment there about the patch itself, and I'll iterate.

Comment 14 Ramon de C Valle 2012-01-24 14:56:05 UTC
Hi Bastien, do you have any update on this?

Comment 19 Stefan Cornelius 2012-05-18 14:02:01 UTC

Comment 21 Peter Robinson 2016-03-10 19:55:26 UTC
Upstream is dead, It's been retired in F-24+
