Security update for the Linux Kernel (Live Patch 29 for SLE 12) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2018:2787-1 Final 1 1 2018-09-21T10:04:52Z current 2018-09-21T10:04:52Z 2018-09-21T10:04:52Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 29 for SLE 12) This update for the Linux Kernel 3.12.61-52_106 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).
