Go toolchain cmd/go Yayım: 2026-05-07 22:41 (6 ay önce)

Açıklama

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.
