Code execution via undisclosed integer overflow
Published Jan 14, 2022 · Updated Sep 16, 2024
Integer overflow in Adobe Acrobat Reader 17.011.30204, 20.004.30017, and 21.007.20099 and earlier allows attackers to execute code. Adobe has not published the affected parser or arithmetic operation beyond identifying an integer overflow or wraparound. Exploitation requires a victim to open a malicious file, after which attacker-supplied code runs with the victim process privileges.
