  - Heap-based Buffer Overflow in the psf_binheader_writef

    allows remote attackers to cause a denial of service
    (application crash) or possibly have unspecified other
    impact.(CVE-2017-12562)

  - It was discovered the fix for CVE-2018-19758
    (libsndfile) was not complete and still allows a read
    beyond the limits of a buffer in wav_write_header()
    function in wav.c. A local attacker may use this flaw
    to make the application crash.(CVE-2019-3832)

  - An issue was discovered in libsndfile 1.0.28. There is
    a buffer over-read in the function i2alaw_array in
    alaw.c that will lead to a denial of
    service.(CVE-2018-19662)

for reading and writing files containing sampled sound.

CVE-2017-8361

The flac_buffer_copy function (flac.c) is affected by a buffer
overflow. This vulnerability might be leveraged by remote attackers to
cause a denial of service, or possibly have unspecified other impact
via a crafted audio file.

CVE-2017-8362

The flac_buffer_copy function (flac.c) is affected by an out-of-bounds
read vulnerability. This flaw might be leveraged by remote attackers
to cause a denial of service via a crafted audio file.

CVE-2017-8363

The flac_buffer_copy function (flac.c) is affected by a heap based OOB
read vulnerability. This flaw might be leveraged by remote attackers
to cause a denial of service via a crafted audio file.

CVE-2017-8365

The i2les_array function (pcm.c) is affected by a global buffer
overflow. This vulnerability might be leveraged by remote attackers to
cause a denial of service, or possibly have unspecified other impact
via a crafted audio file.

CVE-2017-14245 CVE-2017-14246 CVE-2017-17456 CVE-2017-17457

The d2alaw_array() and d2ulaw_array() functions (src/ulaw.c and
src/alaw.c) are affected by an out-of-bounds read vulnerability. This
flaw might be leveraged by remote attackers to cause denial of service
or information disclosure via a crafted audio file.

CVE-2017-14634

The double64_init() function (double64.c) is affected by a
divide-by-zero error. This vulnerability might be leveraged by remote
attackers to cause denial of service via a crafted audio file.

CVE-2018-13139

The psf_memset function (common.c) is affected by a stack-based buffer
overflow. This vulnerability might be leveraged by remote attackers to
cause a denial of service, or possibly have unspecified other impact
via a crafted audio file. The vulnerability can be triggered by the
executable sndfile-deinterleave.

CVE-2018-19432

The sf_write_int function (src/sndfile.c) is affected by an
out-of-bounds read vulnerability. This flaw might be leveraged by
remote attackers to cause a denial of service via a crafted audio
file.

CVE-2018-19661 CVE-2018-19662

The i2alaw_array() and i2ulaw_array() functions (src/ulaw.c and
src/alaw.c) are affected by an out-of-bounds read vulnerability. This
flaw might be leveraged by remote attackers to cause denial of service
or information disclosure via a crafted audio file.

For Debian 8 'Jessie', these problems have been fixed in version
1.0.25-9.1+deb8u2.

We recommend that you upgrade your libsndfile packages.
