CVE-2024-30348

Code execution via U3D buffer overrun

Published Apr 2, 2024 · Updated Aug 2, 2024

Out-of-bounds write in U3D parsing in Foxit PDF Reader and PDF Editor allows context-dependent attackers to execute code via a crafted PDF. The U3D parser fails to validate user-supplied data before writing it past the end of an allocated buffer. A target must open the crafted file or visit a malicious page, and successful exploitation runs attacker-controlled code in the current process.
