No installation issues
From comments in MCC:
Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players.
So at CLI:
$ sndfile-resample -to 48000 Zapfenstreich.wav Zapf1.wav
Input File    : Zapfenstreich.wav
Sample Rate   : 44100
Input Frames  : 8596790

SRC Ratio     : 1.088435
Converter     : Medium Sinc Interpolator

Output file   : Zapf1.wav
Sample Rate   : 48000
Output Frames : 9357051
 resulting file is a bit larger than original one, that was to be expected. Plays equally well in Parole.

Advisory uploaded ex Comment 2; but I corrected the CVE-id in the text to that in the title (which I checked): CVE-2017-7697

Testing M5 64 bit

Needed to install the 'progs' pkg.
 $ sndfile-resample -h
gives useful info; but -by <amount> is not explained.

BEFORE the update:-
 lib64samplerate0-0.1.8-5.mga5
 libsamplerate-progs-0.1.8-5.mga5
Tried the PoC and its demonstration given in Comment 2:
 https://blogs.gentoo.org/ago/2017/04/11/libsamplerate-global-buffer-overflow-in-calc_output_single-src_sinc-c/
 https://github.com/asarubbo/poc/blob/master/00262-libsamplerate-globaloverflow-calc_output_single
but it did *not* fail as ilustrated in the first link above:
 $ sndfile-resample -to 24000 -c 1 sampleratePoC out
 Input File    : sampleratePoC
 Sample Rate   : 152690
 Input Frames  : 38388006656
 SRC Ratio     : 0.157181
 Converter     : Medium Sinc Interpolator
 Output file   : out
 Sample Rate   : 24000
 Output Frames : 1287

UPDATEd to:
- lib64samplerate0-0.1.9-1.mga5.x86_64
- libsamplerate-progs-0.1.9-1.mga5.x86_64
Result with the PoC identical.

 $ sndfile-resample -to 36000 BachKBconcerto.wav out
 $ sndfile-resample -to 36000 track1.flac out
produced a good output files (listened to with Parole).

FWIW:
 $ sndfile-resample -to 36000 BachKBconcerto.ogg out
hogged the processor for a very long time, but finished. However, the output was not good. It does not accept .mp3 files.

Update looks good, validating.
