Synopsis

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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. (CVE-2019-20427)

Note that Nessus relies on the presence of the package as reported by the vendor.
