  "details": "libcurl might in some circumstances reuse the wrong connection for SMB(S) transfers.  libcurl features a pool of recent connections so that subsequent requests can reuse an existing connection to avoid overhead.  When reusing a connection a range of criteria must be met. Due to a logical error in the code, a network transfer operation that was requested by an application could wrongfully reuse an existing SMB connection to the same server that was using a different \"share\" than the new subsequent transfer should.  This could in unlucky situations lead to the download of the wrong file or the upload of a file to the wrong place. When this happens, the same credentials are used and the server name is the same.",
