An update that solves two vulnerabilities can now be installed.
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).
