Application crash via loudness heap over-read
Published Feb 8, 2021 · Updated Aug 4, 2024
Out-of-bounds read in libmysofa 0.5 through 1.1 allows attackers to crash applications by opening a crafted SOFA file. The loudness function advances beyond the allocated HRTF sample buffer and dereferences unallocated heap memory while mysofa_open processes the file. Exploitation requires an application to pass the malicious file to mysofa_open; the reported consequence is a segmentation-fault service interrupt.
