BIT-golang-2026-39819 — Invoking "go bug" follows symlinks in predictable temporary filenames in cmd/go

Affected: Bitnami: golang

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.
