CVE-2021-24032
MEDIUMZstandard 1.4.1-1.4.8 - Insecure Inherited Permissions via Output File Creation
Title source: llmDescription
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.
