SUSE SLES12 Security Update : kernel (SUSE-SU-2019:0326-1)

high Nessus Plugin ID 122113

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 3.12.61-52_128 fixes one issue.

The following security issue was fixed :

CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time could make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user could cause a host kernel memory corruption and a system panic.
Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bsc#1119947).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or 'zypper patch'.

Alternatively you can run the command listed for your product :

SUSE Linux Enterprise Server 12-LTSS:zypper in -t patch SUSE-SLE-SERVER-12-2019-321=1 SUSE-SLE-SERVER-12-2019-322=1 SUSE-SLE-SERVER-12-2019-323=1 SUSE-SLE-SERVER-12-2019-324=1 SUSE-SLE-SERVER-12-2019-325=1 SUSE-SLE-SERVER-12-2019-326=1 SUSE-SLE-SERVER-12-2019-327=1 SUSE-SLE-SERVER-12-2019-328=1
