SUSE SLES12 Security Update : kernel (SUSE-SU-2018:2787-1)

high Nessus Plugin ID 117663

Language:

Synopsis

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

Description

This update for the Linux Kernel 3.12.61-52_122 fixes several issues.

The following security issues were fixed :

CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).

CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).

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'.
