gpp_maybe Security update for the linux kernel
SUSE-SLE-SERVER-12-SP1-2018-954

The SUSE Linux Enterprise 12 SP1 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). The following non-security bugs were fixed: - x86/bugs: Make sure that _TIF_SSBD does not end up in _TIF_ALLWORK_MASK (bsc#1093215). - x86/bugs: correctly force-disable IBRS on !SKL systems (bsc#1092497). - x86/cpu/intel: Introduce macros for Intel family numbers (bsc#985025). - x86/speculation: Remove Skylake C2 from Speculation Control microcode blacklist (bsc#1087845).
