  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-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).
- ... [Please see the references for more information on the vulnerabilities]");
