What is CVE-2026-111376?

FreeRDP versions prior to 3.32.0 contain a vulnerability within the Windows client's CliprdrStream_New, which can be exploited by malicious RDP servers. By providing clipboard responses that consist of fewer than eight bytes when a user pastes a remote file, attackers can cause the client to either crash or corrupt the stream size during a FILECONTENTS_SIZE request. This vulnerability poses a significant risk as it can lead to application instability and data integrity issues.
