LZ4 before 1.9.2 has a heap-based buffer overflow in LZ4_write32 (related to LZ4_compress_destSize), affecting applications that call LZ4_compress_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."
LZ4 versiones anteriores a 1.9.2, presenta un desbordamiento de búfer en la región heap de la memoria en LZ4_write32 (relacionado con la función LZ4_compress_destSize), que afecta a las aplicaciones que llaman a LZ4_compress_fast con una entrada larga. (Este problema también puede conllevar a la corrupción de datos). NOTA: el fabricante indica que "solo unos pocos usos específicos / poco comunes de la API están en riesgo".
