MGASA-2021-0323 - Updated zstd packages fix a security vulnerability

Publication date: 09 Jul 2021
URL: https://advisories.mageia.org/MGASA-2021-0323.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2021-24032

Description:
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).
