An update that fixes two vulnerabilities is now available.

Description:

This update for the Linux Kernel 3.12.74-60_64_115 fixes several issues.

The following security issues were fixed:

- CVE-2019-11487: The Linux kernel allowed page->_refcount reference
count
overflow, with resultant use-after-free issues, if about 140 GiB of RAM
exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c,
mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests
(bsc#1133191).
- CVE-2018-5390: Linux kernel could be forced to make very expensive calls
to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming
packet which can lead to a denial of service (bsc#1102682).
