How to fix?

There is no fixed version for lz4.


lz4 is a lossless compression algorithm, providing compression speed at 400 MB/s per core, scalable with multi-cores CPU.

Affected versions of this package are vulnerable to Improper Input Validation. The lz4_uncompress function in lib/lz4/lz4_decompress.c on 32-bit platforms might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run that would be improperly handled by programs not complying with an API limitation.
