Doc Text:
A flaw was found in FreeRDP. A remote attacker controlling a Remote Desktop gateway can cause a Denial of Service (DoS) by returning a crafted HTTP response containing an unrecognized Content-Type header with a semicolon and a nonzero Content-Length. This flaw triggers an infinite loop in the client's response parser, exhausting client processor resources and causing the connection thread to hang indefinitely.

Description OSIDB Bzimport 2026-10-14 23:04:08 UTC
FreeRDP from 3.0.0 before 3.32.0 contains an infinite loop vulnerability in http_response_recv() that allows malicious gateways to exhaust client CPU via crafted Content-Type headers. Attackers controlling a gateway can return a nonzero Content-Length with a semicolon-containing unrecognized Content-Type, pinning a client thread at full CPU indefinitely.
