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

Description

This update for the Linux Kernel 4.4.121-92_146 fixes several issues.

The following security issues were fixed :

CVE-2020-25668: Fixed a concurrency use-after-free in con_font_op (bsc#1178622).

CVE-2020-25645: Fixed an issue which traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted (bsc#1177513).

CVE-2020-0429: Fixed a memory corruption due to a use after free which could have led to to local privilege escalation (bsc#1176931).
