Information disclosure via unchecked U3D object access
Published Dec 19, 2025 · Updated Dec 19, 2025
Out-of-bounds reads in Foxit PDF Reader and PDF Editor 2025.2.1 and earlier allow attackers to corrupt memory via crafted 3D files. The U3D parser reads beyond an allocated object because it neither confirms the target object's existence nor sufficiently bounds-checks malformed PRC or U3D data. The flaw affects Windows and requires a user to open a malicious PDF or visit an attacker-controlled page; it can disclose process memory.
