CVE-2026-39819Invoking "go bug" follows symlinks in predictable temporary filenames in cmd/go

Go toolchain cmd/go Veröffentlicht: 2026-05-07 22:41 (vor 6 Monaten)

Beschreibung

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.
