The remote SUSE host is missing one or more security updates.
The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2018-19824: A local user could exploit a use-after-free in the ALSA driver by supplying a malicious USB Sound device (with zero interfaces) that is mishandled in usb_audio_probe in sound/usb/card.c (bnc#1118152). CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removed entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry could remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769). CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). CVE-2018-18445: Faulty computation of numeric bounds in the BPF verifier permitted out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandled 32-bit right shifts (bnc#1112372). CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). CVE-2017-18224: fs/ocfs2/aops.c omitted use of a semaphore and consequently had a race condition for access to the extent tree during read operations in DIRECT mode, which allowed local users to cause a denial of service (BUG) by modifying a certain e_cpos field (bnc#1084831). CVE-2017-16533: The usbhid_parse function in drivers/hid/usbhid/hid-core.c allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066674). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
