    description stack buffer overflow in the native Bluetooth stack A stack buffer overflow flaw was found in the way the Bluetooth subsystem of the Linux kernel processed pending L2CAP configuration responses from a client. On systems with the stack protection feature enabled in the kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other than s390x and ppc64[le]), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to crash the system. Due to the nature of the stack protection feature, code execution cannot be fully ruled out, although we believe it is unlikely. On systems without the stack protection feature (ppc64[le]; the Bluetooth modules are not built on s390x), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to remotely execute arbitrary code on the system with ring 0 (kernel) privileges. (CVE-2017-1000251) dereferencing NULL payload with nonzero length A flaw was found in the implementation of associative arrays where the add_key systemcall and KEYCTL_UPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer dereference (kernel oops). (CVE-2017-15274) xfs: unprivileged user kernel oops A flaw was found where the XFS filesystem code mishandles a user-settable inode flag in the Linux kernel prior to 4.14-rc1. This can cause a local denial of service via a kernel panic.(CVE-2017-14340) Information leak in the scsi driver The sg_ioctl() function in 'drivers/scsi/sg.c' in the Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for '/dev/sg0'. (CVE-2017-14991) kvm: nVMX: L2 guest could access hardware(L0) CR8 register Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization (nVMX) feature enabled (nested=1), is vulnerable to a crash due to disabled external interrupts. As L2 guest could access (r/w) hardware CR8 register of the host(L0). In a nested visualization setup, L2 guest user could use this flaw to potentially crash the host(L0) resulting in DoS.

    description The SUSE Linux Enterprise 12 GA LTS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bnc#1064388). - CVE-2015-9004: kernel/events/core.c in the Linux kernel mishandled counter grouping, which allowed local users to gain privileges via a crafted application, related to the perf_pmu_register and perf_event_open functions (bnc#1037306). - CVE-2016-10229: udp.c in the Linux kernel allowed remote attackers to execute arbitrary code via UDP traffic that triggers an unsafe second checksum calculation during execution of a recv system call with the MSG_PEEK flag (bnc#1032268). - CVE-2016-9604: The handling of keyrings starting with '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to manipulate privileged keyrings, was fixed (bsc#1035576) - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line (bnc#1039456). - CVE-2017-1000365: The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the argument and environment pointers into account, which allowed attackers to bypass this limitation. (bnc#1039354). - CVE-2017-1000380: sound/core/timer.c in the Linux kernel is vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time (bnc#1044125). - CVE-2017-10661: Race condition in fs/timerfd.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bnc#1053152). - CVE-2017-11176: The mq_notify function in the Linux kernel did not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allowed attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact (bnc#1048275). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the 'CR8-load exiting' and 'CR8-store exiting' L0 vmcs02 controls exist in cases where L1 omits the 'use TPR shadow' vmcs12 control, which allowed KVM L2 guest OS users to obtain read and write access to the hardware CR8 register (bnc#1058507). - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. (bnc#1053148). - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667). - CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588). - CVE-2017-14106: The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel allowed local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path (bnc#1056982). - CVE-2017-14140: The move_pages system call in mm/migrate.c in the Linux kernel doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179). - CVE-2017-15265: Use-after-free vulnerability in the Linux kernel allowed local users to have unspecified impact via vectors related to /dev/snd/seq (bnc#1062520). - CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - CVE-2017-2647: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving a NULL value for a certain match field, related to the keyring_search_iterator function in keyring.c (bnc#1030593). - CVE-2017-6951: The keyring_search_aux function in security/keys/keyring.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call for the 'dead' type (bnc#1029850). - CVE-2017-7482: A potential memory corruption was fixed in decoding of krb5 principals in the kernels kerberos handling. (bnc#1046107). - CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel mishandled reference counts, which allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879). - CVE-2017-7518: The Linux kernel was vulnerable to an incorrect debug exception(#DB) error. It could occur while emulating a syscall instruction and potentially lead to guest privilege escalation. (bsc#1045922). - CVE-2017-7541: The brcmf_cfg80211_mgmt_tx function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted NL80211_CMD_FRAME Netlink packet (bnc#1049645). - CVE-2017-7542: The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel allowed local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket (bnc#1049882). - CVE-2017-7889: The mm subsystem in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allowed local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c (bnc#1034405). - CVE-2017-8106: The handle_invept function in arch/x86/kvm/vmx.c in the Linux kernel 3.12 allowed privileged KVM guest OS users to cause a denial of service (NULL pointer dereference and host OS crash) via a single-context INVEPT instruction with a NULL EPT pointer (bnc#1035877). - CVE-2017-8831: The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a 'double fetch' vulnerability (bnc#1037994). - CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bnc#1038544). - CVE-2017-8924: The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel allowed local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow (bnc#1037182 bsc#1038982). - CVE-2017-8925: The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel allowed local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling (bnc#1037183 bsc#1038981). - CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel did not consider that the nexthdr field may be associated with an invalid option, which allowed local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls (bnc#1039882). - CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883). - CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885). - CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069). - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel is too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bnc#1041431).

    description The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes. This update adds mitigations for various side channel attacks against modern CPUs that could disclose content of otherwise unreadable memory (bnc#1068032). - CVE-2017-5753: Local attackers on systems with modern CPUs featuring deep instruction pipelining could use attacker controllable speculative execution over code patterns in the Linux Kernel to leak content from otherwise not readable memory in the same address space, allowing retrieval of passwords, cryptographic keys and other secrets. This problem is mitigated by adding speculative fencing on affected code paths throughout the Linux kernel. - CVE-2017-5715: Local attackers on systems with modern CPUs featuring branch prediction could use mispredicted branches to speculatively execute code patterns that in turn could be made to leak other non-readable content in the same address space, an attack similar to CVE-2017-5753. This problem is mitigated by disabling predictive branches, depending on CPU architecture either by firmware updates and/or fixes in the user-kernel privilege boundaries. Please contact your CPU / hardware vendor for potential microcode or BIOS updates needed for this fix. As this feature can have a performance impact, it can be disabled using the 'nospec' kernel commandline option. - CVE-2017-5754: Local attackers on systems with modern CPUs featuring deep instruction pipelining could use code patterns in userspace to speculative executive code that would read otherwise read protected memory, an attack similar to CVE-2017-5753. This problem is mitigated by unmapping the Linux Kernel from the user address space during user code execution, following a approach called 'KAISER'. The terms used here are 'KAISER' / 'Kernel Address Isolation' and 'PTI' / 'Page Table Isolation'. This feature is disabled on unaffected architectures. This feature can be enabled / disabled by the 'pti=[on|off|auto]' or 'nopti' commandline options. The following security bugs were fixed : - CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel (BlueZ) was vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space (bnc#1057389). - CVE-2017-11600: net/xfrm/xfrm_policy.c in the Linux kernel did not ensure that the dir value of xfrm_userpolicy_id is XFRM_POLICY_MAX or less, which allowed local users to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via an XFRM_MSG_MIGRATE xfrm Netlink message (bnc#1050231). - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667). - CVE-2017-13167: An elevation of privilege vulnerability in the kernel sound timer was fixed. (bnc#1072876). - CVE-2017-14106: The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel allowed local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path (bnc#1056982). - CVE-2017-14140: The move_pages system call in mm/migrate.c in the Linux kernel didn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179). -

CVE-2017-16538: drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux kernel allowed local users to cause a denial of service (general protection fault and system crash) or possibly have unspecified other impact via a crafted USB device, related to a missing warm-start check and incorrect attach timing (dm04_lme2510_frontend_attach versus dm04_lme2510_tuner) (bnc#1066569). - CVE-2017-16649: The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel allowed local users to cause a denial of service (divide-by-zero error and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067085). - CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bnc#1069702 1069708). - CVE-2017-17450: net/netfilter/xt_osf.c in the Linux kernel did not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allowed local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces (bnc#1071695 1074033). -

    description Security Fix(es) : An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. * Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. This fix specifically addresses S390 processors. (CVE-2017-5715, Important) * Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. This fix specifically addresses S390 and PowerPC processors. (CVE-2017-5753, Important) * Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. This fix specifically addresses PowerPC processors. (CVE-2017-5754, Important)

    description From Red Hat Security Advisory 2018:0151 : An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system.

    description According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - arch/x86/kvm/mmu.c in the Linux kernel through 4.13.5, when nested virtualisation is used, does not properly traverse guest pagetable entries to resolve a guest virtual address, which allows L1 guest OS users to execute arbitrary code on the host OS or cause a denial of service (incorrect index during page walking, and host OS crash), aka an MMU potential stack buffer overrun.(CVE-2017-12188) - A vulnerability was found in the Key Management sub component of the Linux kernel, where when trying to issue a KEYTCL_READ on negative key would lead to a NULL pointer dereference. A local attacker could use this flaw to crash the kernel.(CVE-2017-12192) - security/keys/keyctl.c in the Linux kernel before 4.11.5 does not consider the case of a NULL payload in conjunction with a nonzero length value, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192.(CVE-2017-15274) - Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.(CVE-2017-1000111) - Use-after-free vulnerability in the Linux kernel before 4.14-rc5 allows local users to have unspecified impact via vectors related to /dev/snd/seq.(CVE-2017-15265) - net/packet/af_packet.c in the Linux kernel before 4.13.6 allows local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346.(CVE-2017-15649) - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel before 4.13.4 allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for /dev/sg0.(CVE-2017-14991) - An exploitable memory corruption flaw was found in the Linux kernel. The append path can be erroneously switched from UFO to non-UFO in ip_ufo_append_data() when building an UFO packet with MSG_MORE option. If unprivileged user namespaces are available, this flaw can be exploited to gain root privileges.(CVE-2017-1000112) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - A vulnerability was found in the key management subsystem of the Linux kernel. An update on an uninstantiated key could cause a kernel panic, leading to denial of service (DoS).(CVE-2017-15299) - It was found that fanout_add() in 'net/packet/af_packet.c' in the Linux kernel, before version 4.13.6, allows local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free bug.(CVE-2017-15649) - The keyctl_read_key function in security/keys/keyctl.c in the Key Management subcomponent in the Linux kernel before 4.13.5 does not properly consider that a key may be possessed but negatively instantiated, which allows local users to cause a denial of service (OOPS and system crash) via a crafted KEYCTL_READ operation.(CVE-2017-12192) - The Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled (nested=1), was vulnerable to a stack buffer overflow issue. The vulnerability could occur while traversing guest page table entries to resolve guest virtual address(gva).

    description The SUSE Linux Enterprise 12 SP1 LTS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bnc#1064388). - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667). - CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - CVE-2017-15265: Use-after-free vulnerability in the Linux kernel allowed local users to have unspecified impact via vectors related to /dev/snd/seq (bnc#1062520). - CVE-2017-1000365: The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the argument and environment pointers into account, which allowed attackers to bypass this limitation. (bnc#1039354). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the 'CR8-load exiting' and 'CR8-store exiting' L0 vmcs02 controls exist in cases where L1 omits the 'use TPR shadow' vmcs12 control, which allowed KVM L2 guest OS users to obtain read and write access to the hardware CR8 register (bnc#1058507). - CVE-2017-14106: The tcp_disconnect function in net/ipv4/tcp.c in the Linux kernel allowed local users to cause a denial of service (__tcp_select_window divide-by-zero error and system crash) by triggering a disconnect within a certain tcp_recvmsg code path (bnc#1056982). - CVE-2017-14140: The move_pages system call in mm/migrate.c in the Linux kernel doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179). - CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588). - CVE-2017-10661: Race condition in fs/timerfd.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bnc#1053152). - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. (bnc#1053148). - CVE-2017-8831: The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a 'double fetch' vulnerability (bnc#1037994). - CVE-2017-7482: A potential memory corruption was fixed in decoding of krb5 principals in the kernels kerberos handling. (bnc#1046107). - CVE-2017-7542: The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel allowed local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket (bnc#1049882). - CVE-2017-11176: The mq_notify function in the Linux kernel did not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allowed attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact (bnc#1048275). - CVE-2017-7541: The brcmf_cfg80211_mgmt_tx function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg8021 1.c in the Linux kernel allowed local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted NL80211_CMD_FRAME Netlink packet (bnc#1049645). - CVE-2017-7518: The Linux kernel was vulnerable to an incorrect debug exception(#DB) error. It could occur while emulating a syscall instruction and potentially lead to guest privilege escalation. (bsc#1045922). - CVE-2017-8924: The edge_bulk_in_callback function in drivers/usb/serial/io_ti.c in the Linux kernel allowed local users to obtain sensitive information (in the dmesg ringbuffer and syslog) from uninitialized kernel memory by using a crafted USB device (posing as an io_ti USB serial device) to trigger an integer underflow (bnc#1037182 bsc#1038982). - CVE-2017-8925: The omninet_open function in drivers/usb/serial/omninet.c in the Linux kernel allowed local users to cause a denial of service (tty exhaustion) by leveraging reference count mishandling (bnc#1037183 bsc#1038981). - CVE-2017-1000380: sound/core/timer.c in the Linux kernel was vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents might have been disclosed when a read and an ioctl happen at the same time (bnc#1044125). - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel is too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bnc#1041431). - CVE-2017-1000363: Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (could happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) could overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line (bnc#1039456). - CVE-2017-9076: The dccp_v6_request_recv_sock function in net/dccp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039885). - CVE-2017-9077: The tcp_v6_syn_recv_sock function in net/ipv6/tcp_ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1040069). - CVE-2017-9075: The sctp_v6_create_accept_sk function in net/sctp/ipv6.c in the Linux kernel mishandled inheritance, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls, a related issue to CVE-2017-8890 (bnc#1039883). - CVE-2017-9074: The IPv6 fragmentation implementation in the Linux kernel did not consider that the nexthdr field may be associated with an invalid option, which allowed local users to cause a denial of service (out-of-bounds read and BUG) or possibly have unspecified other impact via crafted socket and send system calls (bnc#1039882). - CVE-2017-7487: The ipxitf_ioctl function in net/ipx/af_ipx.c in the Linux kernel mishandled reference counts, which allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a failed SIOCGIFADDR ioctl call for an IPX interface (bnc#1038879). - CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bnc#1038544). - CVE-2017-7889: The mm subsystem in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, which allowed local users to read or write to kernel memory locations in the first megabyte (and bypass slab-allocation access restrictions) via an application that opens the /dev/mem file, related to arch/x86/mm/init.c and drivers/char/mem.c (bnc#1034405). The following new features were implemented : - the r8152 network driver was updated to support Realtek RTL8152/RTL8153 Based USB Ethernet Adapters (fate#321482) The update package also includes non-security fixes.

    title SUSE SLES12 Security Update : kernel (SUSE-SU-2017:2908-1) (KRACK) (Stack Clash)
  • NASL family Ubuntu Local Security Checks
    NASL id UBUNTU_USN-3469-2.NASL
    description USN-3469-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Anthony Perard discovered that the Xen virtual block driver did not properly initialize some data structures before passing them to user space. A local attacker in a guest VM could use this to expose sensitive information from the host OS or other guest VMs. (CVE-2017-10911) Bo Zhang discovered that the netlink wireless configuration interface in the Linux kernel did not properly validate attributes when handling certain requests. A local attacker with the CAP_NET_ADMIN could use this to cause a denial of service (system crash). (CVE-2017-12153) It was discovered that the nested KVM implementation in the Linux kernel in some situations did not properly prevent second level guests from reading and writing the hardware CR8 register. A local attacker in a guest could use this to cause a denial of service (system crash). It was discovered that the key management subsystem in the Linux kernel did not properly restrict key reads on negatively instantiated keys. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-12192) It was discovered that an integer overflow existed in the sysfs interface for the QLogic 24xx+ series SCSI driver in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-14051) It was discovered that the ATI Radeon framebuffer driver in the Linux kernel did not properly initialize a data structure returned to user space. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-14156) Dave Chinner discovered that the XFS filesystem did not enforce that the realtime inode flag was settable only on filesystems on a realtime device. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14340) ChunYu Wang discovered that the iSCSI transport implementation in the Linux kernel did not properly validate data structures. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-14489) It was discovered that the generic SCSI driver in the Linux kernel did not properly initialize data returned to user space in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-14991) Dmitry Vyukov discovered that the Floating Point Unit (fpu) subsystem in the Linux kernel did not properly handle attempts to set reserved bits in a task's extended state (xstate) area. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-15537) Pengfei Wang discovered that the Turtle Beach MultiSound audio device driver in the Linux kernel contained race conditions when fetching from the ring-buffer. A local attacker could use this to cause a denial of service (infinite loop). (CVE-2017-9984, CVE-2017-9985). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-16649: The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel allowed local users to cause a denial of service (divide-by-zero error and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067085). - CVE-2017-16535: The usb_get_bos_descriptor function in drivers/usb/core/config.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066700). - CVE-2017-15102: The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel allowed local users (who are physically proximate for inserting a crafted USB device) to gain privileges by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference (bnc#1066705). - CVE-2017-16531: drivers/usb/core/config.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device, related to the USB_DT_INTERFACE_ASSOCIATION descriptor (bnc#1066671). - CVE-2017-16529: The snd_usb_create_streams function in sound/usb/card.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066650). - CVE-2017-16525: The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel allowed local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup (bnc#1066618). - CVE-2017-16537: The imon_probe function in drivers/media/rc/imon.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066573). - CVE-2017-16536: The cx231xx_usb_probe function in drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066606). - CVE-2017-16527: sound/usb/mixer.c in the Linux kernel allowed local users to cause a denial of service (snd_usb_mixer_interrupt use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1066625). - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients (bnc#1063667). - CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - CVE-2017-15265: Race condition in the ALSA subsystem in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted /dev/snd/seq ioctl calls, related to sound/core/seq/seq_clientmgr.c and sound/core/seq/seq_ports.c (bnc#1062520). - CVE-2017-14489: The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel allowed local users to cause a denial of service (panic) by leveraging incorrect length validation (bnc#1059051). - CVE-2017-14340: The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel did not verify that a filesystem has a realtime device, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory (bnc#1058524). - CVE-2017-14140: The move_pages system call in mm/migrate.c in the Linux kernel doesn't check the effective uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable despite ASLR (bnc#1057179). - CVE-2017-14051: An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) by leveraging root access (bnc#1056588). - CVE-2017-10661: Race condition in fs/timerfd.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations that leverage improper might_cancel queueing (bnc#1053152). - CVE-2017-12762: In /drivers/isdn/i4l/isdn_net.c: A user-controlled buffer is copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow. (bnc#1053148). - CVE-2017-8831: The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a 'double fetch' vulnerability (bnc#1037994). - CVE-2017-1000112: An exploitable memory corruption due to UFO to non-UFO path switch was fixed. (bnc#1052311 bnc#1052365). 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.
