Linux Distros Unpatched Vulnerability : CVE-2019-20429

high Nessus Plugin ID 251269

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

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 an out-of-bounds read and panic (via a modified lm_bufcount field) due to the lack of validation for specific fields of packets sent by a client.
 This is caused by interaction between sptlrpc_svc_unwrap_request and lustre_msg_hdr_size_v2.
 (CVE-2019-20429)

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

Solution

There is no known solution at this time.
