CVE-2021-24031alpinezstd+4
EPSS score0.46%
In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions. Correct file permissions (matching the input) would only be set at completion time. Output files could therefore be readable or writable to unintended parties.CVE-2021-24032alpinezstd+4EPSS score0.35%
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-2022-4899debianlibzstd+14EPSS score1.59%
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-2019-11922alpinezstd+9EPSS score1.42%
