New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

This update for the Linux Kernel 4.4.74-92_38 fixes several issues.
The following security issues were fixed :

- CVE-2018-1000199: A bug in x86 debug register handling of ptrace() could lead to memory corruption, possibly a denial of service or privilege escalation (bsc#1090036).

- CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allowed attackers to gain privileges via unspecified vectors (bsc#1088268).

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 for SAP 12-SP2:zypper in -t patch SUSE-SLE-SAP-12-SP2-2018-880=1
