"The version of sox installed on the remote host is prior to 14.4.1-7. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2023-2231 advisory.

  - 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)

  - 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)

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