  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-3620: Local attackers on baremetal systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data. (bnc#1087081).
- CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system. (bnc#1089343).
- CVE-2018-14734: drivers/infiniband/core/ucma.c allowed ucma_leave_multicast to access a certain data structure after a cleanup step in ucma_process_join, which allowed attackers to cause a denial of service (use-after-free) (bnc#1103119).
- CVE-2018-13053: The alarm_timer_nsleep function in kernel/time/alarmtimer.c had 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. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416).
- CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used (bnc#1098016 bnc#1100418).

The following non-security bugs were fixed:

- bcache: add backing_request_endio() for bi_end_io (bsc#1064233).
- bcache: add CACHE_SET_IO_DISABLE to struct cache_set flags (bsc#1064233).
- bcache: add io_disable to struct cached_dev (bsc#1064233).
- bcache: add journal statistic (bsc#1076110).
- bcache: Add __printf annotation to __bch_check_keys() (bsc#1076110).
- bcache: add stop_when_cache_set_failed option to backing device (bsc#1064233).
- bcache: add wait_for_kthread_stop() in bch_allocator_thread() (bsc#1064233).
- bcache: Annotate switch fall-through (bsc#1076110).
- bcache: closures: move control bits one bit right (bsc#1076110).
- bcache: correct flash only vols (check all uuids) (bsc#1064233).
- bcache: count backing device I/O error for writeback I/O (bsc#1064233).
- bcache: do not attach backing with duplicate UUID (bsc#1076110).
- bcache: Fix a compiler warning in bcache_device_init() (bsc#1076110).
- bcache: fix ... [Please see the references for more information on the vulnerabilities]");
