Описание
FreeRDP before 3.31.0 contains a buffer over-read vulnerability in the rts_read_result function within the RPC gateway transport parser. Attackers can send a malicious BIND_ACK PDU with a truncated result entry to trigger an out-of-bounds read causing process abort.
A flaw was found in FreeRDP. A remote attacker can exploit a buffer over-read vulnerability within the RPC (Remote Procedure Call) gateway transport parser by sending a malicious BIND_ACK Protocol Data Unit (PDU) with a truncated result entry. This can lead to a process abort, resulting in a Denial of Service (DoS).
Меры по смягчению последствий
To mitigate this issue, restrict network access to any FreeRDP instance operating in a server or gateway role, limiting connections to trusted clients or networks. If FreeRDP is used as a client, avoid connecting to untrusted or malicious RDP servers to prevent exploitation.
