CVE-2021-40783

Code execution via out-of-bounds WAV parsing

Published Dec 20, 2021 · Updated Apr 23, 2025

Memory corruption in Adobe Premiere Rush 1.5.16 and earlier allows local users to execute code by opening a malicious WAV file. The WAV import path accesses memory beyond the end of a buffer while processing attacker-controlled file data. Exploitation requires a user to open the file, and resulting code runs with that user's privileges.
