Description Vasyl Kaigorodov 2015-03-05 11:53:29 UTC 
It was reported [1] that the OAuth implementation in librest, a helper library for RESTful services part of the GNOME project, incorrectly truncates the pointer returned by the rest_proxy_call_get_url function call, leading to an application crash, or worse.

Comment 1 Vasyl Kaigorodov 2015-03-23 11:13:07 UTC 
Created rest tracking bugs for this issue:

Affects: fedora-all [bug 1204682]
Comment 3 Peter Robinson 2015-10-04 02:42:28 UTC 
Vasyl: why is this a bug in Fedora?

The commit referenced landed upstream in September 2015, we're running 0.7.93 across all current Fedora releases (21 ->24) which was released with the fix in March 2015. It's also referenced in comment 2 [1] in the upstream bug that this was fixed upstream

Peter, it was an issue for Fedora when this flaw bug was filed, see https://bugzilla.redhat.com/show_bug.cgi?id=1204682 (Fedora security tracker bug for this issue).
I.e. - Fedora was affected, the problem was resolved in BZ 1204682, no further actions required from Fedora side.
Hope this answers your question.

Not sure why I only just got alerts then, all of the emails dated a few days ago, didn't take note of the dates in the actual BZ bits above

Hi Peter,

CVE/Flaw bugs are not supposed to be closed until all affected products are fixed. May be you wanted to close bug that was opened for Fedora.
