Title of the patch: Security update for the Linux Kernel

Description of the patch: The SUSE Linux Enterprise 11 SP4 kernel was updated to 3.0.101-94 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2017-5551: tmpfs: clear S_ISGID when setting posix ACLs (bsc#1021258). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device NOTE: this vulnerability existed because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2016-5696: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#989152). - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provided an incomplete set of requirements for setattr operations that underspecified removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. (bnc#1014746). - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531). - CVE-2012-6704: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option (bnc#1013542). - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038). - CVE-2016-9685: Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations (bnc#1012832). - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2013-6368: The KVM subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address (bnc#853052). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7916: Race condition in the environ_read function in fs/proc/base.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete (bnc#1010467). - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833).
