CVE-2026-73242 FreeRDP: Kerberos GSS Wrap-token `EC` field is unbounded, causing an out-of-bounds decrypt in `kerberos_DecryptMessage`

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP's winpr/libwinpr/sspi/Kerberos/kerberos.c kerberosDecryptMessage function fails to bound the peer-controlled GSS Wrap-token EC field before using it with RRC in IOV pointer offsets, allowing a malicious RDP...

CVE-2026-73241

FreeRDP vulnerability CVE-2026-73241 affects the server-side RDSTLS implementation (libfreerdp/core/rdstls.c). An attacker-supplied RDSTLS_TYPE_CAPABILITIES PDU can be processed while the server awaits RDSTLS_TYPE_AUTHREQ, leaving resultCode as RDSTLS_RESULT_SUCCESS and allowing a remote unauthen...

CVE-2026-72745

A flaw was found in FreeRDP. A malicious peer, either a server or client, can exploit an out-of-bounds vulnerability during CredSSP/NLA authentication. By supplying a large 'extra count' EC value in a Kerberos GSS Wrap token, an attacker can cause the decryption operation to access memory outside...

CVE-2026-72746

A flaw was found in FreeRDP. An unauthenticated remote attacker could bypass the server-side authentication in the RDSTLS Remote Desktop Services Transport Layer Security handshake. By sending a Capabilities PDU instead of the expected Authentication Request PDU, the server incorrectly processes...

EUVD-2026-56136

FreeRDP before 3.30.0 contains a server-side authentication bypass in the RDSTLS handshake. When a server is configured with RdstlsSecurity = TRUE, the handshake dispatches inbound PDUs based solely on the attacker-supplied wire pduType without verifying that the received PDU is the one required ...
