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).

Описание
It was found that the raw midi kernel driver does not protect against concurrent access which leads to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status() which are part of snd_rawmidi_ioctl() handler in rawmidi.c file. A malicious local attacker could possibly use this for privilege escalation.

Linux kernel versions 4.9+ can be forced to make very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming packet which can lead to a denial of service.
