CVE-2020-10904Public exploit

Code execution via U3D out-of-bounds write

Published Apr 22, 2020 · Updated Aug 4, 2024

Out-of-bounds write in Foxit PhantomPDF 9.7.1.29511 allows remote attackers to execute arbitrary code via malicious PDF U3D objects. The U3DBrowser parser fails to validate attacker-supplied U3D object data before writing past an allocated object boundary. Exploitation requires a user to visit a malicious page or open the malicious PDF, and code runs in the current process context.
