  script_tag(name:"insight", value:"The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-3639: Information leaks using 'Memory Disambiguation' feature
 in modern CPUs were mitigated, aka 'Spectre Variant 4' (bnc#1087082).
 A new boot commandline option was introduced,
'spec_store_bypass_disable', which can have following values:
 - auto: Kernel detects whether your CPU model contains an implementation
 of Speculative Store Bypass and picks the most appropriate mitigation.
 - on: disable Speculative Store Bypass
 - off: enable Speculative Store Bypass
 - prctl: Control Speculative Store Bypass per thread via prctl.
 Speculative Store Bypass is enabled for a process by default. The
 state of the control is inherited on fork.
 - seccomp: Same as 'prctl' above, but all seccomp threads will disable
 SSB unless they explicitly opt out.
 The default is 'seccomp', meaning programs need explicit opt-in into the mitigation.
 Status can be queried via the
/sys/devices/system/cpu/vulnerabilities/spec_store_bypass file, containing:
 - 'Vulnerable'
 - 'Mitigation: Speculative Store Bypass disabled'
 - 'Mitigation: Speculative Store Bypass disabled via prctl'
 - 'Mitigation: Speculative Store Bypass disabled via prctl and seccomp'
- CVE-2018-1000199: An address corruption flaw was discovered while
 modifying a h/w breakpoint via 'modify_user_hw_breakpoint' routine, an
 unprivileged user/process could use this flaw to crash the system kernel
 resulting in DoS OR to potentially escalate privileges on a the system.
 (bsc#1089895)
- CVE-2018-10675: The do_get_mempolicy function in mm/mempolicy.c allowed
 local users to cause a denial of service (use-after-free) or possibly
 have unspecified other impact via crafted system calls (bnc#1091755).
- CVE-2017-5715: The retpoline mitigation for Spectre v2 has been enabled
 also for 32bit x86.
- CVE-2017-5753: Spectre v1 mitigations have been improved by the versions
 merged from the upstream kernel.
The following non-security bugs were fixed:
- Update config files. Set CONFIG_RETPOLINE=y for i386.
- x86/espfix: Fix return stack in do_double_fault() (bsc#1085279).
- xen-netfront: fix req_prod check to avoid RX hang when index wraps
 (bsc#1046610).");
