Rsync symbolic-link race condition
CVE-2024-12747 is a race condition in the rsync server's handling of symbolic links. The provided content states that rsync's default behavior is to skip symbolic links, but an attacker can replace a regular file with a symbolic link at a precise time during processing, bypassing that default protection and causing rsync to traverse the symlink. The issue affects the rsync server implementation, not the client application, and is reported in rsync versions 3.3.0 and earlier; other provided context also describes the affected range as >= 3.2.7 and < 3.4.0. This flaw can expose files outside the intended synchronization scope when the daemon processes attacker-controlled or attacker-raceable filesystem content.
