Security update for the Linux Kernel (Live Patch 16 for SLE 15) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2020:0940-1 Final 1 1 2020-04-07T09:13:44Z current 2020-04-07T09:13:44Z 2020-04-07T09:13:44Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 16 for SLE 15) This update for the Linux Kernel 4.12.14-150_41 fixes several issues. The following security issues were fixed: - CVE-2020-1749: Fixed an issue in the networking protocols in encrypted IPsec tunnel (bsc#1165631) - CVE-2019-5108: Fixed an issue where by triggering AP to send IAPP location updates for stations before the required authentication process has completed could have led to denial-of-service (bsc#1159913).

An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.

When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
