Code execution via undisclosed out-of-bounds write
Published Jan 14, 2022 · Updated Sep 16, 2024
Out-of-bounds write in Adobe Acrobat Reader 21.007.20099 and earlier allows attackers to execute code through a malicious file. Adobe has not disclosed the affected parser, memory-write operation, or malformed file element that crosses the buffer boundary. Exploitation requires a user to open the file, and resulting code runs with that user's privileges on Windows or macOS.
