How to fix?

There is no fixed version for Echo:latest golang-1.19.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-1.19 package and not the golang-1.19 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
