| Description | ## Description [Simd](https://github.com/ermig1979/Simd) has heap-buffer-overflow src/Simd/SimdMemoryStream.h:199:27 in ReadUnsigned<unsigned char> ## version ```shell commit a1580a5fb13e2f8c78715afb0bc47e44519ccd32 ``` ## harnss From https://github.com/google/oss-fuzz/blob/master/projects/simd/simd_load_fuzzer.cpp ```c++ #include <stdint.h> #include <string.h> #include <stdlib.h> #include "Test/TestUtils.h" extern "C" int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size){ if (size<5) { return 0; } Test::View::Format formats[4] = {Test::View::Gray8, Test::View::Bgr24, Test::View::Bgra32, Test::View::Rgb24}; for(int i=0; i<4; i++) { Test::View dst1; dst1.Load(data, size, formats[i]); } return 0; } ``` ## Proof of Concept The poc can be obtained from Google Drive: https://drive.google.com/drive/folders/1z0JBsZ-QR3RsuAf-uyit_ZGXCh0rEvFq?usp=sharing ```shell $ ./simd_load_fuzzer f3d3a0b9-f889-4853-86b3-6cd46a34fc3e INFO: Running with entropic power schedule (0xFF, 100).
