Description Pedro Sampaio 2018-02-27 17:02:02 UTC 
An issue was discovered in GNU libcdio before 2.0.0. There is a double free in get_cdtext_generic() in lib/driver/_cdio_generic.c.

Upstream patch:

Comment 1 Pedro Sampaio 2018-02-27 17:08:59 UTC 
Created libcdio tracking bugs for this issue:

Affects: fedora-all [bug 1549713]
Comment 6 rocky 2018-03-13 14:59:39 UTC 
I am trying to understand the this bug tracking system. 

When I read:

> Affects: fedora-all [bug 1549713]

What does "fedora-all" mean? As noted previously, the bug was introduced sometime after 0.90 (definitely in 0.94) but fixed in 2.0.0
Comment 7 Adrian Reber 2018-03-13 15:02:20 UTC 
I understand 'fedora-all' as all active releases. Currently that would be F26 and F27 with libcdio-0.94 and F-28 and rawhide with libcdio-2.0.0

I patched libcdio for F26 and F27. F28 and rawhide should be on the safe side with 2.0.0.
Comment 8 rocky 2018-03-13 15:12:42 UTC 
Thanks for the clarification. So I gather rawhide is not considered to be in "fedora-all"?

Not a big deal. I'm just trying to understand these things in detail and wondering about how accurate such trackers are. Since I happen to know what's up with this one, I'm can it as a gauge for other bug reports where I really have no idea.
Comment 9 rocky 2018-03-13 15:14:09 UTC 
I'm can it -> I can use it
