CVE-2022-24369

Code execution via JP2 buffer size overflow

Published Feb 18, 2022 · Updated Aug 3, 2024

Out-of-bounds write in Foxit PDF Reader 11.1.0.52543 allows remote attackers to execute code via a crafted JP2 image. An integer overflow in the JP2 parser's memory-size calculation allocates an undersized buffer before crafted image data is written past its end. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current process.
