Fluid Attacks Database

Description

The "go bug" command writes to two files with predictable names in the system temporary directory (for example, "/tmp"). An attacker with access to the temporary directory can create a symlink in one of these names, causing "go bug" to overwrite the target of the symlink.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
