Title
FreeRDP 3.9.0 before 3.32.0 RDPEAR NDR Scalar Out-of-Bounds Read
Summary
FreeRDP from 3.9.0 before 3.32.0 contains an out-of-bounds read vulnerability in the RDPEAR NDR scalar readers, which check value length before consuming alignment padding. Malicious or compromised RDP servers can send crafted unaligned RDPEAR payloads, such as CreateApReqAuthenticatorReq messages, to clients using Remote Credential Guard, causing over-reads and potentially crashing the client process.
