Information disclosure via out-of-bounds U3D parsing
Published Nov 14, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Open Design Alliance PRC SDK before 2022.10 allows attackers to expose process memory through a crafted U3D file. The U3D parser processes crafted data by reading past the end of an allocated buffer during conversion to PRC. A victim must convert the malicious file; the direct impact is information disclosure, while code execution requires chaining with another flaw.
