The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had an integer overflow via a large relative timeout because ktime_add_safe is not used (bnc#1099924). - CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group.
