The rsync developers have discovered a security related problem in rsync, a fast remote file copy program, which offers an attacker to access files outside of the defined directory. To exploit this path-sanitizing bug, rsync has to run in daemon mode with the chroot option being disabled. It does not affect the normal send/receive filenames that specify what files should be transferred. It does affect certain option paths that cause auxiliary files to be read or written.
