Описание
FreeRDP versions before 3.31.0 contain an integer overflow in WinPR's Stream_EnsureRemainingCapacity function that allows remote attackers to cause denial of service. A malicious RD Gateway peer can send a WebSocket Ping frame with a crafted 64-bit extended payload length to trigger integer wraparound, resulting in a double free that crashes the FreeRDP client during connection.
A flaw was found in FreeRDP. A remote attacker, specifically a malicious RD Gateway peer, could send a crafted WebSocket Ping frame with an extended payload length. This action triggers an an integer overflow in the Stream_EnsureRemainingCapacity function, leading to an integer wraparound and a double free vulnerability. Successful exploitation results in a denial of service, causing the FreeRDP client to crash during connection.
Меры по смягчению последствий
To mitigate this issue, FreeRDP clients should only connect to trusted and verified Remote Desktop Gateway servers. Connecting to untrusted or unverified servers may expose the client to denial of service attacks.
