Technical details

An out-of-bounds write vulnerability (CWE-787) exists in Adobe Media Encoder. The flaw is triggered when the application processes a specially crafted file, leading to memory corruption. An attacker can leverage this to execute arbitrary code in the context of the current user. The attack vector is local, requiring user interaction (UI:R) to open the malicious file. Adobe has addressed this in versions 26.3 and 25.6.6.
