CVE-2019-20427

In the Lustre file system before 2.12.3, the ptlrpc module has a buffer overflow and panic, and possibly remote code execution, due to the lack of validation for specific fields of packets sent by a client. Interaction between req_capsule_get_size and tgt_brw_write leads to a tgt_shortio2pages integer signedness error.
