User-assisted code execution via stack buffer overflow
Published Jan 18, 2023 · Updated Mar 5, 2025
Stack-based buffer overflow in Adobe Acrobat Reader 22.003.20282 and earlier allows attackers to execute code through a malicious file. The affected range is 22.003.20281 and earlier on macOS and 20.005.30418 and earlier for Classic 2020 on both platforms. Adobe has not disclosed the affected parser or the operation that overruns stack storage; exploitation requires a victim to open the file and runs code as the current user.
