  script_tag(name:"insight", value:"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.
 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).
- 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-2018-3620: 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).
The following non-security bugs were fixed:
- bcache: Add __printf annotation to __bch_check_keys() (bsc#1064232).
- bcache: Annotate switch fall-through (bsc#1064232).
- bcache: Fix a compiler warning in bcache_device_init() (bsc#1064232).
- bcache: Fix indentation (bsc#1064232).
- bcache: Fix kernel-doc warnings (bsc#1064232).
- bcache: Fix, improve efficiency of closure_sync() (bsc#1064232).
- bcache: Reduce the number of sparse complaints about lock imbalances
 (bsc#1064232).
- bcache: Remove an unused variable (bsc#1064232).
- bcache: Suppress more warnings about set-but-not-used variables
 (bsc#1064232).
- bcache: Use PTR_ERR_OR_ZERO() (bsc#1064232).
- bcache: add CACHE_SET_IO_DISABLE to struct cache_set flags (bsc#1064232).
- bcache: add backing_request_endio() for bi_end_io (bsc#1064232).
- bcache: add io_disable to struct cached_dev (bsc#1064232).
- bcache: add journal statistic ... [Please see the references for more information on the vulnerabilities]");
