A floating point exception (divide-by-zero) issue was discovered in SoX in functon startread() of wav.c file. An attacker with a crafted wav file, could cause an application to crash.

The version of sox installed on the remote host is prior to 14.4.1-7. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-3032 advisory.

    A floating point exception (divide-by-zero) issue was discovered in SoX in functon startread() of wav.c     file. An attacker with a crafted wav file, could cause an application to crash. (CVE-2021-33844)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2023:0329-1 advisory.

  - 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)

  - 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 floating point exception (divide-by-zero) issue was discovered in SoX in functon startread() of wav.c     file. An attacker with a crafted wav file, could cause an application to crash. (CVE-2021-33844)

  - A flaw was found in sox 14.4.1. The lsx_adpcm_init function within libsox leads to a global-buffer-     overflow. This flaw allows an attacker to input a malicious file, leading to the disclosure of sensitive     information. (CVE-2021-3643)

  - A heap-based buffer overflow vulnerability exists in the sphere.c start_read() functionality of Sound     Exchange libsox 14.4.2 and master commit 42b3557e. A specially-crafted file can lead to a heap buffer     overflow. An attacker can provide a malicious file to trigger this vulnerability. (CVE-2021-40426)

  - 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 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)
