Synopsis

The Adobe Media Encoder instance installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Adobe Media Encoder installed on the remote Windows or macOS host is prior to 26.5.3, 25.6.x prior or equal to 25.6.6. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB26-103 advisory.

 - Out-of-bounds Write (CWE-787) potentially leading to Arbitrary code execution (CVE-2026-113541, CVE-2026-113543, CVE-2026-113545, CVE-2026-113547)

 - Incorrect Authorization (CWE-863) potentially leading to Arbitrary code execution (CVE-2026-82002)

 - NULL Pointer Dereference (CWE-476) potentially leading to Application denial-of-service (CVE-2026-113539)

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

Solution

Upgrade to Adobe Media Encoder version 26.5.3, 27.0 or later.
