Details

LZ4 before 1.9.2 has a heap-based buffer overflow in LZ4write32 (related to LZ4compressdestSize), affecting applications that call LZ4compress_fast with a large input. (This issue can also lead to data corruption.) NOTE: the vendor states "only a few specific / uncommon usages of the API are at risk."
