Executive brief
Adobe Media Encoder, a professional video and audio processing application, is affected by a security flaw that could allow an attacker to take control of a user's system. To exploit this, an attacker must trick a user into opening a specially crafted malicious file. If successful, the attacker could execute unauthorized commands or install software with the same permissions as the logged-in user.
Technical details
An out-of-bounds write vulnerability (CWE-787) exists in Adobe Media Encoder versions 26.0.2, 25.6.4 and earlier. The flaw is triggered when the application processes a malformed file, leading to memory corruption. An attacker can leverage this to achieve arbitrary code execution within the security context of the current user. The attack vector is local, requiring a user to manually open a malicious file (User Interaction: Required). Adobe has addressed this in newer versions, and users are advised to update to the latest available releases.
