rsync: rsync < 3.5.0 Command Injection via Multiple Code Paths

A command injection vulnerability in rsync allows remote attackers to execute arbitrary commands by supplying shell metacharacters or newlines in unsanitized inputs, such as hostnames or hostspecs. This impacts multiple vectors—including the RSYNCCONNECTPROG variable, daemon hooks, rsync-ssl, and...

rsync: rsync: TLS Certificate Validation Bypass allows interception of encrypted sessions

A flaw was found in the rsync-ssl wrapper script's TLS certificate validation. An on-path attacker can present self-signed or invalid certificates to intercept, decrypt, or tamper with encrypted sessions. Because rsync fails to validate the certificate against a trusted CA or verify hostname...
