Timeline

2026-08-01first spoke of it: 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 allocation on the server.NVD

FreeRDP: FreeRDP: Denial of Service due to RDPEI message processing

cvss 6.5 cvss_vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H cwe CWE-20 packages freerdp-2:3.10.3-12.el10_2.10, freerdp-2:3.10.3-3.el10_0.16 severity moderate source
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 allocation on the server.
