The version of Adobe Media Encoder installed on the remote host is prior to 15.4.3, or 22.x prior to 22.1.1. It is, therefore, affected by multiple vulnerabilities, as follows:
Adobe Media Encoder versions 15.4.2 and earlier, and 22.x prior to 22.1.1 have an arbitrary code execution vulnerability, due to access of memory location after end of buffer and out-of-bounds read. (CVE-2021-43756, CVE-2021-43757)
Adobe Media Encoder versions 15.4.2 and earlier, and 22.x prior to 22.1.1 have an out-of-bounds read vulnerability. Successful exploitation could lead to privilege escalation. (CVE-2021-43757, CVE-2021-43758, CVE-2021-43759, CVE-2021-43760)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
