"The version of Adobe Media Encoder installed on the remote macOS host is prior to 15.4.2. It is, therefore, affected by
multiple vulnerabilities as referenced in the APSB21-99 advisory.

  - Adobe Media Encoder version 15.4.1 (and earlier) are affected by a memory corruption vulnerability. An
    unauthenticated attacker could leverage this vulnerability to achieve arbitrary code execution in the
    context of the current user. Exploitation of this issue requires user interaction in that a victim must
    open a malicious file. (CVE-2021-43013)

  - Adobe Media Encoder version 15.4.1 (and earlier) is affected by a memory corruption vulnerability due to
    insecure handling of a malicious file, potentially resulting in arbitrary code execution in the context of
    the current user. User interaction is required to exploit this vulnerability. (CVE-2021-40777,
    CVE-2021-40779, CVE-2021-40780)

  - Adobe Media Encoder 15.4.1 (and earlier) is affected by a Null pointer dereference vulnerability when
    parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to achieve
    an application denial-of-service in the context of the current user. Exploitation of this issue requires
    user interaction in that a victim must open a malicious file. (CVE-2021-40778, CVE-2021-40781,
    CVE-2021-40782)

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