  - sox: buffer overflow read vulnerability (CVE-2021-3643)

  - sox: heap-based buffer overflow vulnerability exists in the sphere.c start_read() function
    (CVE-2021-40426)

  - The startread function in wav.c in Sound eXchange (SoX) 14.4.2 allows remote attackers to cause a denial
    of service (divide-by-zero error and application crash) via a crafted wav file. (CVE-2017-11332)

  - The read_samples function in hcom.c in Sound eXchange (SoX) 14.4.2 allows remote attackers to cause a
    denial of service (invalid memory read and application crash) via a crafted hcom file. (CVE-2017-11358)

  - The wavwritehdr function in wav.c in Sound eXchange (SoX) 14.4.2 allows remote attackers to cause a denial
    of service (divide-by-zero error and application crash) via a crafted snd file, during conversion to a wav
    file. (CVE-2017-11359)

  - There is a heap-based buffer overflow in the ImaExpandS function of ima_rw.c in Sound eXchange (SoX)
    14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.
    (CVE-2017-15370)

  - There is a reachable assertion abort in the function sox_append_comment() in formats.c in Sound eXchange
    (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an audio file.
    (CVE-2017-15371)

  - There is a stack-based buffer overflow in the lsx_ms_adpcm_block_expand_i function of adpcm.c in Sound
    eXchange (SoX) 14.4.2. A Crafted input will lead to a denial of service attack during conversion of an
    audio file. (CVE-2017-15372)

  - In lsx_aiffstartread in aiff.c in Sound eXchange (SoX) 14.4.2, there is a Use-After-Free vulnerability
    triggered by supplying a malformed AIFF file. (CVE-2017-15642)

  - An issue was discovered in SoX 14.4.2. lsx_make_lpf in effect_i_dsp.c has an integer overflow on the
    result of multiplication fed into malloc. When the buffer is allocated, it is smaller than expected,
    leading to a heap-based buffer overflow. (CVE-2019-8354)

  - An issue was discovered in SoX 14.4.2. In xmalloc.h, there is an integer overflow on the result of
    multiplication fed into the lsx_valloc macro that wraps malloc. When the buffer is allocated, it is
    smaller than expected, leading to a heap-based buffer overflow in channels_start in remix.c.
    (CVE-2019-8355)

  - An issue was discovered in SoX 14.4.2. One of the arguments to bitrv2 in fft4g.c is not guarded, such that
    it can lead to write access outside of the statically declared array, aka a stack-based buffer overflow.
    (CVE-2019-8356)

  - An issue was discovered in SoX 14.4.2. lsx_make_lpf in effect_i_dsp.c allows a NULL pointer dereference.
    (CVE-2019-8357)

  - A vulnerability was found in SoX, where a heap-buffer-overflow occurs in function lsx_read_w_buf() in
    formats_i.c file. The vulnerability is exploitable with a crafted file, that could cause an application to
    crash. (CVE-2021-23159)

  - A vulnerability was found in SoX, where a heap-buffer-overflow occurs in function startread() in hcom.c
    file. The vulnerability is exploitable with a crafted hcomn file, that could cause an application to
    crash. (CVE-2021-23172)

  - In SoX 14.4.2, there is a floating-point exception in lsx_aiffstartwrite in aiff.c in libsox.a.
    (CVE-2022-31650)

  - In SoX 14.4.2, there is an assertion failure in rate_init in rate.c in libsox.a. (CVE-2022-31651)

  - A floating point exception vulnerability was found in sox, in the lsx_aiffstartwrite function at
    sox/src/aiff.c:622:58. This flaw can lead to a denial of service. (CVE-2023-26590)

  - A floating point exception vulnerability was found in sox, in the read_samples function at
    sox/src/voc.c:334:18. This flaw can lead to a denial of service. (CVE-2023-32627)

  - A heap buffer overflow vulnerability was found in sox, in the startread function at sox/src/hcom.c:160:41.
    This flaw can lead to a denial of service, code execution, or information disclosure. (CVE-2023-34318)

  - A heap buffer overflow vulnerability was found in sox, in the lsx_readbuf function at
    sox/src/formats_i.c:98:16. This flaw can lead to a denial of service, code execution, or information
    disclosure. (CVE-2023-34432)
