NVD Description

Note: Versions mentioned in the description apply only to the upstream lz4 package and not the lz4 package as distributed by Ubuntu.

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."
