CVE-2026-67289

FreeRDP before 3.29.0 affected versions = 3.28.0 does not validate CRLF and control characters in the server-controlled RDP redirection TargetNetAddress field. This value is copied into the client's ServerHostname and, when the client connects through an HTTP proxy, is written directly into the...

CVE-2026-64620

FreeRDP before 3.28.0 affected outlength, so out-of-bounds bytes are written before the bounds check. On the server side, when a client selects RDP Standard Security, the encrypted client random is decrypted into a fixed 32-byte buffer. Because the server publishes its RSA public key, an...
