Description Laura Pardo 2018-02-23 21:52:27 UTC
A flaw was found in lame. The II_step_one function in layer2.c in mpglib, as used in libmpgdecoder.a in LAME 3.99.5 and other products, allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted audio file.

Comment 1 Laura Pardo 2018-02-23 21:53:02 UTC
Created lame tracking bugs for this issue:

Affects: epel-all [bug 1548570]
Affects: fedora-all [bug 1548571]

Comment 2 Yaakov Selkowitz 2018-03-29 17:06:15 UTC
The report mentions LAME 3.99.5, but Fedora already has 3.100; is it possible to confirm if this is already fixed thereby?

Comment 3 Laura Pardo 2018-04-03 14:34:14 UTC
Hi Yaakov! Yes, confirmed. It has been fixed in version 3.100

Thanks, does that apply to the rest of this batch as well (bug 1548572, bug 1548576, bug 1548580, and bug 1548583)?
