| Titel | Open Asset Import Library Assimp 6.0.2 / master commit 0581ed5 Uncontrolled Memory Allocation |
|---|
| Beschreibung | The bug occurs in the Q3DImporter::InternReadFile function, where the importer reads the number of materials (numMats) directly from the input file without validation. This value is then used in a call to materials.reserve(numMats) and later in a loop with materials.emplace_back(). Since numMats is attacker-controlled, a malicious file can specify an extremely large value, leading the program to request an allocation far exceeding addressable memory. This results in an allocation-size-too-big error under ASan and causes the process to terminate. |
