______________________________________________________________________________
An update that solves 9 vulnerabilities and has 41 fixes is
now available.
Description:
The SUSE Linux Enterprise 11 SP4 Realtime 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-2015-1142857: On multiple SR-IOV cars it is possible for VF's
assigned to guests to send ethernet flow control pause frames via the
PF. This includes Linux kernel ixgbe driver, i40e/i40evf driver and the
DPDK, additionally multiple vendor NIC firmware is affected
(bnc#1077355).
- CVE-2017-13215: A elevation of privilege vulnerability in the Upstream
kernel skcipher. (bnc#1075908).
- 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-2017-18017: 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-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).
- 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 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).
