CVE-2024-9243

Code execution via unchecked AcroForm object lifetime

Published Nov 22, 2024 · Updated Nov 26, 2024

Use-after-free in Foxit PDF Reader before 2024.3 allows remote attackers to execute arbitrary code through a crafted PDF file. The AcroForm Doc handler performs operations on an object without first validating that the object still exists after its lifetime ends. Exploitation requires the target to visit a malicious page or open a malicious file, and resulting code runs in the current application process.
