CVE-2021-24032 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libzstd package and not the libzstd package as distributed by Debian.
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.
