Fluid Attacks Database

Description

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.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
