Summary
zstd security update
Details

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):

Beginning in v1.4.1 and prior to v1.4.9, due to an incomplete fix for CVE-2021-24031, the Zstandard command-line utility created output files with default permissions and restricted those permissions immediately afterwards. Output files could therefore momentarily be readable or writable to unintended parties.(CVE-2021-24032)
