rsync: TOCTOU symlink race condition allowing local privilege escalation in daemon mode without chroot.

A flaw was found in rsync. An rsync daemon configured with "use chroot = no" is exposed to a time-of-check / time-of-use race on parent path components. A local attacker with write access to a module can replace a parent directory component with a symlink between the receiver's check and its open...
