Overview

Affected versions of this package are vulnerable to Command Injection via unsanitized input in several code paths, including the RSYNC_CONNECT_PROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shell command newline injection. An attacker can execute arbitrary commands by injecting shell metacharacters or newline characters into user-supplied values such as hostnames and hostspecs.
