These requests are used to transfer arbitrary amounts + of memory from clients to servers and back using small SMB + requests and contain two offsets: One offset (A) pointing into + the PDU sent by the client and one (B) to direct the transferred + contents into the buffer built on the server side. While the range + checking for offset (B) is correct, a cut and paste error lets offset + (A) pass completely unchecked against overflow.</p> + <p>The buffers passed into trans, trans2 and nttrans undergo higher-level + processing like DCE/RPC requests or listing directories. The missing + bounds check means that a malicious client can make the server do this + higher-level processing on arbitrary memory contents of the smbd process + handling the request.
