SUSE SLES12 Security Update : cryptctl (SUSE-SU-2021:2137-1)

critical Nessus Plugin ID 151087

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by a vulnerability as referenced in the SUSE-SU-2021:2137-1 advisory.

 Update to version 2.4:

 - CVE-2019-18906: Client side password hashing was equivalent to clear text password storage (bsc#1186226)
 - First step to use plain text password instead of hashed password.
 - Move repository into the SUSE github organization
 - in RPC server, if client comes from localhost, remember its ipv4 localhost address instead of ipv6 address
 - tell a record to clear expired pending commands upon saving a command result; introduce pending commands RPC test case
 - avoid hard coding 127.0.0.1 in host ID of alive message test; let system administrator mount and unmount disks by issuing these two commands on key server.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected cryptctl package.
