NVD Description

Note: Versions mentioned in the description apply only to the upstream minio-operator-6-sidecar package and not the minio-operator-6-sidecar package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

The "go tool pack" subcommand (usually used only by the compiler as an internal tool with known-good inputs) does not sanitize output filenames. Extracting a malicious archive file with the "pack" subcommand can write files to arbitrary locations on the filesystem.
