  script_tag(name:"insight", value:"The SUSE Linux Enterprise 11 SP4 kernel was updated to 3.0.101-108.81 to receive various security and bugfixes.

The following security bugs were fixed:
CVE-2018-18281: An issue was discovered in the Linux kernel, the
 mremap() syscall performs TLB flushes after dropping pagetable locks. If
 a syscall such as ftruncate() removes entries from the pagetables of a
 task that is in the middle of mremap(), a stale TLB entry can 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 issue was discovered in the Linux kernel, 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-2018-18386: drivers/tty/n_tty.c in the Linux kernel 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-2017-7273: The cp_report_fixup function in drivers/hid/hid-cypress.c
 in the Linux kernel 4.x allowed physically proximate attackers to cause
 a denial of service (integer underflow) or possibly have unspecified
 other impact via a crafted HID report (bnc#1031240).

CVE-2017-16533: The usbhid_parse function in
 drivers/hid/usbhid/hid-core.c in the Linux kernel 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).

CVE-2017-1000407: An denial of service issue was discovered in the Linux
 kernel, by flooding the diagnostic port 0x80 an exception can be
 triggered leading to a kernel panic (bnc#1071021).

CVE-2018-9516: An issue was discovered in the Linux kernel, the
 copy_to_user() inside the HID code does not correctly check the length
 before executing (bsc#1108498).

CVE-2018-14633: A security flaw was found in the
 chap_server_compute_md5() function in the ISCSI target code in the Linux
 kernel in a way an authentication request from an ISCSI initiator is
 processed. An unauthenticated remote attacker can cause a stack buffer
 overflow and smash up to 17 bytes of the stack. The attack requires the
 iSCSI target to be enabled on the victim host. Depending on how the
 target's code was built (i.e. depending on a compiler, compile flags and
 hardware architecture) an attack may lead to a system crash and thus to
 a denial-of-service or possibly to a non-authorized access to data
 exported by an iSCSI target. Due to the nature of the flaw, privilege
 escalation cannot be fully ruled out, although we believe it is highly
 unlikely (bnc#1107829).

The following non-security bugs were fixed:
