QA REPRODUCER:

sndfile-deinterleave oob_sf_write_int:2257

should not segfault.
Comment 2 Takashi Iwai 2018-11-23 13:02:52 UTC
This isn't really a security matter; it's nothing but a crash of sndfile-deinterleave program, and not a bug in the library itself.
That is, it's just a function call with wrong arguments from the specific program.

The "fix" in the upstream is to add a check of the channels in sndfile-deinterleave program, and not about the library code.

There is another change about the channel check in the library code that I'll take together in anyway, but that's basically a different issue.
Comment 3 Takashi Iwai 2018-11-23 13:16:12 UTC
And actually this is the dup of bug 1100167, CVE-2018-13139.

In the previous fix, I seem to have forgotten to patch libsndfile-progs.spec, so the bug still remains, but basically the fix patch is there.

I'll resubmit the fix for libsndfile-progs and update the changelog.
