CVE-2026-73242

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-2026-73242

FreeRDP prior to version 3.30.0 is affected. The vulnerability resides in winpr/libwinpr/sspi/Kerberos/kerberos.c within kerberos_DecryptMessage, where the peer-controlled GSS Wrap-token EC field is not bounded before use with RRC in IOV pointer offsets, enabling out-of-bounds reads and in-place ...

CVE-2026-73241

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.30.0, FreeRDP server-side RDSTLS in libfreerdp/core/rdstls.c accepts an attacker-supplied RDSTLSTYPECAPABILITIES PDU while rdstlsserverauthenticate is waiting for RDSTLSTYPEAUTHREQ, leaving resultCode at RDSTLSRESULTSUCCE...

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...

CVE-2026-72746

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 ...

CVE-2026-72745

FreeRDP before 3.30.0 contains an out-of-bounds vulnerability in kerberosDecryptMessage winpr/libwinpr/sspi/Kerberos/kerberos.c. The 16-bit EC extra count field of a peer-supplied GSS Wrap token RFC 4121 is used directly in pointer arithmetic to locate the encrypted regions without being...

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 ...

CVE-2026-72746 FreeRDP before 3.30.0 RDSTLS Server Authentication Bypass via PDU-type Confusion

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 ...

CVE-2026-72746

FreeRDP (before 3.30.0) is affected by a server‑side authentication bypass in the RDSTLS handshake. When RdstlsSecurity is TRUE, inbound PDUs are dispatched by attacker‑supplied pduType without validating the expected PDU step. The rdstls object is calloc‑zeroed, so resultCode defaults to 0 (RDST...

CVE-2026-72746 FreeRDP before 3.30.0 RDSTLS Server Authentication Bypass via PDU-type Confusion

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 ...

CVE-2026-72745

FreeRDP before 3.30.0 contains an out-of-bounds vulnerability in kerberosDecryptMessage winpr/libwinpr/sspi/Kerberos/kerberos.c. The 16-bit EC extra count field of a peer-supplied GSS Wrap token RFC 4121 is used directly in pointer arithmetic to locate the encrypted regions without being...

CVE-2026-72745

FreeRDP before 3.30.0 contains an out-of-bounds vulnerability in kerberos_DecryptMessage() (winpr/libwinpr/sspi/Kerberos/kerberos.c). The 16-bit EC field of a peer-supplied GSS Wrap token is used directly in pointer arithmetic without proper bounds checking, while RRC and the total buffer length ...
