Zstd is a fast lossless compression algorithm. It's backed by a very fast entropy stage,provided by Huff0 and FSE library. It's a real-time compression scenario for zlib levels and has a better compression ratio. Security Fix(es): A vulnerability was found in zstd v1.4.10, where an attacker can supply empty string as an argument to the command line tool to cause buffer overrun.(CVE-2022-4899) An update for zstd is now available for openEuler-22.03-LTS-SP1. openEuler Security has rated this update as having a security impact of high.
