Adobe Media Encoder versions 22.0, 15.4.2 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of sensitive memory. An attacker could leverage this vulnerability to bypass mitigations such as ASLR. Exploitation of this issue requires user interaction in that a victim must open a malicious MP4 file.

The version of Adobe Media Encoder installed on the remote macOS host is prior to 15.4.3, 22.1.1. It is, therefore, affected by multiple vulnerabilities as referenced in the APSB21-118 advisory.

  - Adobe Media Encoder versions 22.0, 15.4.2 (and earlier) are affected by an out-of-bounds read     vulnerability that could lead to disclosure of sensitive memory.
