"The version of mpg123 installed on the remote host is prior to 1.32.9-1. It is, therefore, affected by a vulnerability
as referenced in the ALAS2-2025-2997 advisory.

    An out-of-bounds write flaw was found in mpg123 when handling crafted streams. When decoding PCM, the
    libmpg123 may write past the end of a heap-located buffer. Consequently, heap corruption may happen, and
    arbitrary code execution is not discarded. The complexity required to exploit this flaw is considered high
    as the payload must be validated by the MPEG decoder and the PCM synth before execution. Additionally, to
    successfully execute the attack, the user must scan through the stream, making web live stream content
    (such as web radios) a very unlikely attack vector. (CVE-2024-10573)

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.");
