  - 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)

  - SoX - Sound eXchange 14.4.2 and earlier is affected by: Out-of-bounds Read. The impact is: Denial of
    Service. The component is: read_samples function at xa.c:219. The attack vector is: Victim must open
    specially crafted .xa file. NOTE: this may overlap CVE-2017-18189. (CVE-2019-1010004)

  - An issue was discovered in libsox.a in SoX 14.4.2. In sox-fmt.h (startread function), there is an integer
    overflow on the result of integer addition (wraparound to 0) fed into the lsx_calloc macro that wraps
    malloc. When a NULL pointer is returned, it is used without a prior check that it is a valid pointer,
    leading to a NULL pointer dereference on lsx_readbuf in formats_i.c. (CVE-2019-13590)

  - 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)
