Overview

github.com/cloudflare/golz4 is a Golang interface to LZ4 compression.

Affected versions of this package are vulnerable to Arbitrary Code Execution. Vulnerable versions of the library used the obsolete native LZ4_uncompress() function possibly leading to memory corruption resulting in arbitrary code execution in case of successful exploitation. The fix made sure to use the safe version of the function called LZ4_decompress_safe().
