The SUSE Linux Enterprise 12 SP1 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-2017-18079: drivers/input/serio/i8042.c 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: Prevent guests from sending ethernet     flow control pause frames via the PF (bnc#1077355).

  - CVE-2017-17741: KVM allowed attackers to obtain     potentially sensitive information from kernel memory,     aka a write_mmio stack-based out-of-bounds read     (bnc#1073311).

  - CVE-2017-13215: Prevent elevation of privilege     (bnc#1075908).

  - CVE-2018-1000004: Prevent race condition in the sound     system, this could have lead a deadlock and denial of     service condition (bnc#1076017).

  - CVE-2017-17806: The HMAC implementation did not validate     that the underlying cryptographic hash algorithm is     unkeyed, allowing a local attacker able to use the     AF_ALG-based hash interface     (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash     algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel     stack-based buffer overflow by executing a crafted     sequence of system calls that encounter a missing SHA-3     initialization (bnc#1073874).

  - CVE-2017-17805: The Salsa20 encryption algorithm did not     correctly handle zero-length inputs, allowing a local     attacker able to use the AF_ALG-based skcipher interface     (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of     service (uninitialized-memory free and kernel crash) or     have unspecified other impact by executing a crafted     sequence of system calls that use the blkcipher_walk     API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 were     vulnerable (bnc#1073792).

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

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.
