______________________________________________________________________________
An update that solves 8 vulnerabilities and has 14 fixes is
now available.
Description:
The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive
various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-5715: Systems with microprocessors utilizing speculative
execution and indirect branch prediction may allow unauthorized
disclosure of information to an attacker with local user access via a
side-channel analysis (bnc#1068032).
The previous fix using CPU Microcode has been complemented by building
the Linux Kernel with return trampolines aka "retpolines".
- CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function
did not validate a value that is used during DMA page allocation,
leading to a heap-based out-of-bounds write (related to the
rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621).
- CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in
net/rds/rdma.c mishandled cases where page pinning fails or an invalid
address is supplied, leading to an rds_atomic_free_op NULL pointer
dereference (bnc#1075617).
- CVE-2017-18017: The tcpmss_mangle_packet function in
net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers
to cause a denial of service (use-after-free and memory corruption) or
possibly have unspecified other impact by leveraging the presence of
xt_TCPMSS in an iptables action (bnc#1074488).
- CVE-2017-18079: drivers/input/serio/i8042.c in the Linux kernel allowed
attackers to cause a denial of service (NULL pointer dereference and
system crash) or possibly have unspecified other impact because the
port->exists value can change after it is validated (bnc#1077922).
- CVE-2017-17741: The KVM implementation in the Linux kernel allowed
attackers to obtain potentially sensitive information from kernel
memory, aka a write_mmio stack-based out-of-bounds read, related to
arch/x86/kvm/x86.c and include/trace/events/kvm.h (bnc#1073311).
- CVE-2017-13215: A elevation of privilege vulnerability in the Upstream
kernel skcipher. (bnc#1075908).
- CVE-2018-1000004: In the Linux kernel a race condition vulnerability
exists in the sound system, this can lead to a deadlock and denial of
service condition (bnc#1076017).
The following non-security bugs were fixed:
- cdc-acm: apply quirk for card reader (bsc#1060279).
- Enable CPU vulnerabilities reporting via sysfs
- fork: clear thread stack upon allocation (bsc#1077560).
- kaiser: Set _PAGE_NX only if supported (bnc#1012382, bnc#1076278).
- kbuild: modversions for EXPORT_SYMBOL() for asm (bsc#1074621
bsc#1068032).
- Move kABI fixup for retpolines to proper place.
- powerpc/vdso64: Use double word compare on pointers (bsc#1070781).
- s390: add ppa to the idle loop (bnc#1077406, LTC#163910).
- s390/cpuinfo: show facilities as reported by stfle (bnc#1076849,
LTC#163741).
- storvsc: do not assume SG list is continuous when doing bounce buffers
(bsc#1075410).
- sysfs/cpu: Add vulnerability folder (bnc#1012382).
- sysfs/cpu: Fix typos in vulnerability documentation (bnc#1012382).
- sysfs: spectre_v2, handle spec_ctrl (bsc#1075994 bsc#1075091).
- x86/acpi: Handle SCI interrupts above legacy space gracefully
(bsc#1068984).
- x86/acpi: Reduce code duplication in mp_override_legacy_irq()
(bsc#1068984).
- x86/boot: Fix early command-line parsing when matching at end
(bsc#1068032).
- x86/cpu: Factor out application of forced CPU caps (bsc#1075994
bsc#1075091).
- x86/cpu: Implement CPU vulnerabilites sysfs functions (bnc#1012382).
- x86/CPU: Sync CPU feature flags late (bsc#1075994 bsc#1075091).
- x86/kaiser: Populate shadow PGD with NX bit only if supported by
platform (bsc#1076154 bsc#1076278).
- x86/kaiser: use trampoline stack for kernel entry.
- x86/microcode/intel: Disable late loading on model 79 (bsc#1054305).
- x86/microcode/intel: Extend BDW late-loading further with LLC size check
(bsc#1054305).
- x86/microcode/intel: Extend BDW late-loading with a revision check
(bsc#1054305).
- x86/microcode: Rescan feature flags upon late loading (bsc#1075994
bsc#1075091).
- x86/retpolines/spec_ctrl: disable IBRS on !SKL if retpolines are active
(bsc#1068032).
- x86/spec_ctrl: handle late setting of X86_FEATURE_SPEC_CTRL properly
(bsc#1075994 bsc#1075091).
- x86/spectre_v2: fix ordering in IBRS initialization (bsc#1075994
bsc#1075091).
- x86/spectre_v2: nospectre_v2 means nospec too (bsc#1075994 bsc#1075091).
