SUSE SLES11 Security Update : kernel (SUSE-SU-2018:0555-1) (Meltdown) (Spectre)

Critical Nessus Plugin ID 107055

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 SP4 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-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. (bnc#1077355).

- 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 existed in the sound system, this can lead to a deadlock and denial of service condition (bnc#1076017).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
