An update that solves 9 vulnerabilities and has 27 fixes is
now available.

Description:

The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to 4.4.121 to
receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-8781: The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c
had an integer-overflow vulnerability that allowed local users with
access to the udldrmfb driver to obtain full read and write permissions
on kernel physical pages, resulting in a code execution in kernel space
(bnc#1090643).
- CVE-2018-10124: The kill_something_info function in kernel/signal.c
might have allowed local users to cause a denial of service via an
INT_MIN argument (bnc#1089752).
- CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might have
allowed local users to cause a denial of service by triggering an
attempted use of the -INT_MIN value (bnc#1089608).
- CVE-2017-18257: The __get_data_block function in fs/f2fs/data.c in the
Linux kernel allowed local users to cause a denial of service (integer
overflow and loop) via crafted use of the open and fallocate system
calls with an FS_IOC_FIEMAP ioctl. (bnc#1088241)
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel
function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious
NCPFS servers to crash the kernel or execute code (bnc#1086162).
- CVE-2018-8043: The unimac_mdio_probe function in
drivers/net/phy/mdio-bcm-unimac.c did not validate certain resource
availability, which allowed local users to cause a denial of service
(NULL pointer dereference) (bnc#1084829).
- CVE-2018-7740: The resv_map_release function in mm/hugetlb.c allowed
local users to cause a denial of service (BUG) via a crafted application
that made mmap system calls and has a large pgoff argument to the
remap_file_pages system call (bnc#1084353).
- CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to
potentially escalate their privileges inside a guest. (bsc#1087088)
- CVE-2018-8897: An unprivileged system user could use incorrect set up
interrupt stacks to crash the Linux kernel resulting in DoS issue.
