CVE-2022-24361

Context-dependent code execution via JPEG2000 out-of-bounds write

Published Feb 18, 2022 · Updated Aug 3, 2024

Out-of-bounds write in Foxit PDF Reader 11.1.0.52543 allows context-dependent attackers to execute code via a crafted JPEG2000 image. The JPEG2000 parser accepts oversized image attributes and miscalculates the required allocation, then writes past the allocated structure. Opening a malicious file or visiting a malicious page is required, and successful exploitation runs code in the current process.
