FreeRDP vulnerability

What happened

FreeRDP before 3.29.0 fails to enforce the RESPONSE_SIZE_LIMIT when processing Transfer-Encoding: chunked HTTP responses in http_response_recv_body(). Attackers controlling a malicious RD Gateway endpoint can send oversized chunked response bodies to exhaust client memory resources without triggering the configured size limit.

Affected versions

FreeRDP: before 3.29.0 (semver) Fixed: See vendor advisory.
