the USN-4704-1 advisory.

  - In libsndfile version 1.0.28, an error in the aiff_read_chanmap() function (aiff.c) can be exploited to
    cause an out-of-bounds read memory access via a specially crafted AIFF file. (CVE-2017-6892)

  - Heap-based Buffer Overflow in the psf_binheader_writef function in common.c in libsndfile through 1.0.28
    allows remote attackers to cause a denial of service (application crash) or possibly have unspecified
    other impact. (CVE-2017-12562)

  - An out of bounds read in the function d2alaw_array() in alaw.c of libsndfile 1.0.28 may lead to a remote
    DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point
    values. (CVE-2017-14245)

  - An out of bounds read in the function d2ulaw_array() in ulaw.c of libsndfile 1.0.28 may lead to a remote
    DoS attack or information disclosure, related to mishandling of the NAN and INFINITY floating-point
    values. (CVE-2017-14246)

  - In libsndfile 1.0.28, a divide-by-zero error exists in the function double64_init() in double64.c, which
    may lead to DoS when playing a crafted audio file. (CVE-2017-14634)

  - In libsndfile 1.0.25 (fixed in 1.0.26), a divide-by-zero error exists in the function
    wav_w64_read_fmt_chunk() in wav_w64.c, which may lead to DoS when playing a crafted audio file.
    (CVE-2017-16942)

  - A stack-based buffer overflow in psf_memset in common.c in libsndfile 1.0.28 allows remote attackers to
    cause a denial of service (application crash) or possibly have unspecified other impact via a crafted
    audio file. The vulnerability can be triggered by the executable sndfile-deinterleave. (CVE-2018-13139)

  - An issue was discovered in libsndfile 1.0.28. There is a NULL pointer dereference in the function
    sf_write_int in sndfile.c, which will lead to a denial of service. (CVE-2018-19432)

  - An issue was discovered in libsndfile 1.0.28. There is a buffer over-read in the function i2ulaw_array in
    ulaw.c that will lead to a denial of service. (CVE-2018-19661)

  - 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)

  - There is a heap-based buffer over-read at wav.c in wav_write_header in libsndfile 1.0.28 that will cause a
    denial of service. (CVE-2018-19758)

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
