  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.114 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-2017-15129: A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel The function get_net_ns_by_id() in net/core/net_namespace.c did not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely (bnc#1074839).
- CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the Linux kernel has a race condition in inet->hdrincl that leads to uninitialized stack pointer usage, this allowed a local user to execute code and gain privileges (bnc#1073229).
- CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignored unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service (bnc#1073928).
- CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled states_equal comparisons between the pointer data type and the UNKNOWN_VALUE data type, which allowed local users to obtain potentially sensitive address information, aka a 'pointer leak (bnc#1073928).
- 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-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).
- 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).
