Descrição técnica

FreeRDP before 3.32.2 contains a denial of service vulnerability in the NLA-enabled shadow server when a CredSSP TSRequest omits negoTokens. Unauthenticated attackers can send a crafted seven-byte TSRequest containing only the version field to trigger a fatal WINPR_ASSERT and abort the server process.

——11FreeRDP 3.0.0 before 3.32.2 server-side RDP peer input parsing skips the six-byte body of a slow-path input event with an unknown message type without checking it lies within the packet's declared length, causing a WinPR stream assertion failure. A remote RDP client with an active session can send a truncated unknown input event to abort assertion-enabled server processes, causing denial of service.8h

——5The MongoDB C Driver does not validate the type or format of a namespace field returned by the server in a query response. A MongoDB endpoint that a client application connects to, without needing any credentials, can return a malformed value in that field. This causes the client application process to terminate, and can also cause the driver to read memory outside an allocated buffer and to send a small amount of the application's own uninitialized heap memory back to the endpoint in a follow-up command. The impact is limited to the process that embeds the driver.2d

——8FreeRDP before 3.32.2 contains a denial of service vulnerability that allows malicious servers or unauthenticated peers to abort clients or proxies via oversized X.224 routing tokens. Attackers can send an oversized LoadBalanceInfo in a Server Redirection PDU, or a 240–247 byte token to a FixedTarget freerdp-proxy, triggering a tpdu_write_header assertion that crashes the process.2d

——4FreeRDP before 3.32.2 allows a client assertion abort because rdpgfx_on_data_received rejects only negative zgfx_decompress status and passes the resulting null output pointer to Stream_StaticConstInit. A malicious RDP server can send a zero-output ZGFX payload on the RDPGFX channel after session activation to terminate the client.2d

——7FreeRDP clients from 3.0.0 before 3.32.2 built with verbose WinPR assertions contain a reachable assertion in rts_read_auth_verifier triggered by malformed RTS padding. Attackers controlling an RD Gateway can send a crafted RPC-over-HTTP RTS PDU with inconsistent authentication padding to abort the connecting client process.2d

——5FreeRDP from 3.17.0 before 3.32.2 contains an assertion failure in the RemoteFX differential decoder when verbose WinPR assertions are enabled. A malicious RDP server can send a crafted RemoteFX tile with adjacent LL3 coefficients summing beyond signed 16-bit range to abort the client process.2d
