CVE-2026-67296 FreeRDP before 3.29.0 Denial of Service via RDPEI PDU

FreeRDP before 3.29.0 contains a denial of service vulnerability in the RDPEI server channel handler that fails to validate maximum PDU body length before stream allocation. A malicious RDP client can send a header-only RDPEI message with a large declared body length to force excessive memory...

CVE-2026-67289 FreeRDP before 3.29.0 HTTP Proxy Request Injection via Redirection

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-2026-67296

CVE-2026-67296 affects FreeRDP prior to 3.29.0, where the RDPEI server channel handler may allocate excessive memory if a header-only RDPEI message declares a large body length, enabling a denial-of-service. This is documented in the NVD/CVE entries and CVE listing; no patch details are provided ...

CVE-2026-67293 FreeRDP before 3.29.0 Improper Certificate Hostname Validation

FreeRDP before 3.29.0 affected versions = 3.28.0 contains an improper certificate hostname validation vulnerability. The TLS hostname matcher tlsmatchhostname in libfreerdp/crypto/tls.c treats a wildcard pattern such as .example.com as matching any hostname ending in .example.com, so it incorrect...

CVE-2026-67290

FreeRDP before 3.29.0 contains a heap out-of-bounds read vulnerability in the TSMF FFmpeg decoder when parsing AVC1 MPEG2VIDEOINFO media types with insufficient ExtraData. Attackers can send malformed media format data from a server to trigger a crash by reading fixed offsets without validating...

CVE-2026-67297

FreeRDP prior to 3.29.0 contains a flaw in http_response_recv_body() where RESPONSE_SIZE_LIMIT is not enforced for Transfer-Encoding: chunked HTTP responses.
