The 4.12.8 stable kernel update contains a number of important fixes across the tree.

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

According to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :

  - An integer overflow vulnerability in     ip6_find_1stfragopt() function was found. A local     attacker that has privileges (of CAP_NET_RAW) to open     raw socket can cause an infinite loop inside the     ip6_find_1stfragopt() function.

  - Race condition in fs/timerfd.c in the Linux kernel     before 4.10.15 allows 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.

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     could use this flaw to elevate their privileges on the     system.

  - Andrey Konovalov discovered a race condition in the UDP     Fragmentation Offload (UFO) code in the Linux kernel. A     local attacker could use this to cause a denial of     service or execute arbitrary code.

  - Kernel memory corruption due to a buffer overflow was     found in brcmf_cfg80211_mgmt_tx() function in Linux     kernels from v3.9-rc1 to v4.13-rc1. The vulnerability     can be triggered by sending a crafted NL80211_CMD_FRAME     packet via netlink. This flaw is unlikely to be     triggered remotely as certain userspace code is needed     for this. An unprivileged local user could use this     flaw 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 we believe it is unlikely.

  - The mq_notify function in the Linux kernel through     4.11.9 does not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a     Netlink socket, it allows attackers to possibly cause a     situation where a value may be used after being freed     (use after free) which may lead to memory corruption or     other unspecified other impact.

  - The tcp_disconnect function in net/ipv4/tcp.c in the     Linux kernel before 4.12 allows 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.

  - 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 (bsc#1038564).

  - CVE-2016-10200: Race condition in the L2TPv3 IP     Encapsulation feature in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the     SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and     net/l2tp/l2tp_ip6.c (bnc#1028415)

  - 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 (bsc#1030593).

  - CVE-2017-2671: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel was too late in     obtaining a certain lock and consequently could not     ensure that disconnect function calls are safe, which     allowed local users to cause a denial of service (panic)     by leveraging access to the protocol value of     IPPROTO_ICMP in a socket system call (bnc#1031003)

  - CVE-2017-5669: The do_shmat function in ipc/shm.c in the     Linux kernel did not restrict the address calculated by     a certain rounding operation, which allowed local users     to map page zero, and consequently bypass a protection     mechanism that exists for the mmap system call, by     making crafted shmget and shmat system calls in a     privileged context (bnc#1026914)

  - CVE-2017-5970: The ipv4_pktinfo_prepare function in     net/ipv4/ip_sockglue.c in the Linux kernel allowed     attackers to cause a denial of service (system crash)     via (1) an application that made crafted system calls or     possibly (2) IPv4 traffic with invalid IP options     (bsc#1024938)

  - CVE-2017-5986: Race condition in the     sctp_wait_for_sndbuf function in net/sctp/socket.c in     the Linux kernel allowed local users to cause a denial     of service (assertion failure and panic) via a     multithreaded application that peels off an association     in a certain buffer-full state (bsc#1025235)

  - CVE-2017-6074: The dccp_rcv_state_process function in     net/dccp/input.c in the Linux kernel mishandled     DCCP_PKT_REQUEST packet data structures in the LISTEN     state, which allowed local users to obtain root     privileges or cause a denial of service (double free)     via an application that made an IPV6_RECVPKTINFO     setsockopt system call (bnc#1026024)

  - CVE-2017-6214: The tcp_splice_read function in     net/ipv4/tcp.c in the Linux kernel allowed remote     attackers to cause a denial of service (infinite loop     and soft lockup) via vectors involving a TCP packet with     the URG flag (bnc#1026722)

  - CVE-2017-6348: The hashbin_delete function in     net/irda/irqueue.c in the Linux kernel improperly     managed lock dropping, which allowed local users to     cause a denial of service (deadlock) via crafted     operations on IrDA devices (bnc#1027178)

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did     not properly restrict association peel-off operations     during certain wait states, which allowed local users to     cause a denial of service (invalid unlock and double     free) via a multithreaded application. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2017-5986 (bnc#1027066)

  - 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 (bsc#1029850).

  - CVE-2017-7184: The xfrm_replay_verify_len function in     net/xfrm/xfrm_user.c in the Linux kernel did not     validate certain size data after an XFRM_MSG_NEWAE     update, which allowed local users to obtain root     privileges or cause a denial of service (heap-based     out-of-bounds access) by leveraging the CAP_NET_ADMIN     capability (bsc#1030573)

  - CVE-2017-7187: The sg_ioctl function in     drivers/scsi/sg.c in the Linux kernel allowed local     users to cause a denial of service (stack-based buffer     overflow) or possibly have unspecified other impact via     a large command size in an SG_NEXT_CMD_LEN ioctl call,     leading to out-of-bounds write access in the sg_write     function (bnc#1030213)

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.

Several vulnerabilities have been discovered in the Linux kernel that may lead to privilege escalation, denial of service or information leaks.

  - CVE-2017-7518     Andy Lutomirski discovered that KVM is prone to an     incorrect debug exception (#DB) error occurring while     emulating a syscall instruction. A process inside a     guest can take advantage of this flaw for privilege     escalation inside a guest.

  - CVE-2017-7558 (stretch only)     Stefano Brivio of Red Hat discovered that the SCTP     subsystem is prone to a data leak vulnerability due to     an out-of-bounds read flaw, allowing to leak up to 100     uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)     Dmitry Vyukov of Google reported that the timerfd     facility does not properly handle certain concurrent     operations on a single file descriptor. This allows a     local attacker to cause a denial of service or     potentially execute arbitrary code.

  - CVE-2017-11600     Bo Zhang reported that the xfrm subsystem does not     properly validate one of the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     can use this to cause a denial of service or potentially     to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229     Jan H. Schoenherr of Amazon discovered that when Linux     is running in a Xen PV domain on an x86 system, it may     incorrectly merge block I/O requests. A buggy or     malicious guest may trigger this bug in dom0 or a PV     driver domain, causing a denial of service or     potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying   back-end block devices, e.g.:echo 2 >   /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)     Adrian Salido of Google reported a race condition in     access to the'driver_override' attribute for platform     devices in sysfs. If unprivileged users are permitted to     access this attribute, this might allow them to gain     privileges.

  - CVE-2017-12153     Bo Zhang reported that the cfg80211 (wifi) subsystem     does not properly validate the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     (in any user namespace with a wifi device) can use this     to cause a denial of service.

  - CVE-2017-12154     Jim Mattson of Google reported that the KVM     implementation for Intel x86 processors did not     correctly handle certain nested hypervisor     configurations. A malicious guest (or nested guest in a     suitable L1 hypervisor) could use this for denial of     service.

  - CVE-2017-14106     Andrey Konovalov discovered that a user-triggerable     division by zero in the tcp_disconnect() function could     result in local denial of service.

  - CVE-2017-14140     Otto Ebeling reported that the move_pages() system call     performed insufficient validation of the UIDs of the     calling and target processes, resulting in a partial     ASLR bypass. This made it easier for local users to     exploit vulnerabilities in programs installed with the     set-UID permission bit set.

  - CVE-2017-14156     'sohu0106' reported an information leak in the atyfb     video driver. A local user with access to a framebuffer     device handled by this driver could use this to obtain     sensitive information.

  - CVE-2017-14340     Richard Wareing discovered that the XFS implementation     allows the creation of files with the 'realtime' flag on     a filesystem with no realtime device, which can result     in a crash (oops). A local user with access to an XFS     filesystem that does not have a realtime device can use     this for denial of service.

  - CVE-2017-14489     ChunYu Wang of Red Hat discovered that the iSCSI     subsystem does not properly validate the length of a     netlink message, leading to memory corruption. A local     user with permission to manage iSCSI devices can use     this for denial of service or possibly to execute     arbitrary code.

  - CVE-2017-14497 (stretch only)     Benjamin Poirier of SUSE reported that vnet headers are     not properly handled within the tpacket_rcv() function     in the raw packet (af_packet) feature. A local user with     the CAP_NET_RAW capability can take advantage of this     flaw to cause a denial of service (buffer overflow, and     disk and memory corruption) or have other impact.

  - CVE-2017-1000111     Andrey Konovalov of Google reported a race condition in     the raw packet (af_packet) feature. Local users with the     CAP_NET_RAW capability can use this for denial of     service or possibly to execute arbitrary code.

  - CVE-2017-1000112     Andrey Konovalov of Google reported a race condition     flaw in the UDP Fragmentation Offload (UFO) code. A     local user can use this flaw for denial of service or     possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881     Armis Labs discovered that the Bluetooth subsystem does     not properly validate L2CAP configuration responses,     leading to a stack-based buffer overflow. This is one of     several vulnerabilities dubbed 'Blueborne'. A nearby     attacker can use this to cause a denial of service or     possibly to execute arbitrary code on a system with     Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)     Jan H. Schoenherr of Amazon reported that the KVM     implementation for Intel x86 processors did not     correctly validate interrupt injection requests. A local     user with permission to use KVM could use this for     denial of service.

  - CVE-2017-1000370     The Qualys Research Labs reported that a large argument     or environment list can result in ASLR bypass for 32-bit     PIE binaries.

  - CVE-2017-1000371     The Qualys Research Labs reported that a large argument     or environment list can result in a stack/heap clash for     32-bit PIE binaries.

  - CVE-2017-1000380     Alexander Potapenko of Google reported a race condition     in the ALSA (sound) timer driver, leading to an     information leak. A local user with permission to access     sound devices could use this to obtain sensitive     information.

Debian disables unprivileged user namespaces by default, but if they are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited by any local user.

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.

Security Fix(es) :

* Out-of-bounds kernel heap access vulnerability was found in xfrm, kernel's IP framework for transforming packets. An error dealing with netlink messages from an unprivileged user leads to arbitrary read/write and privilege escalation. (CVE-2017-7184, Important)

* A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets are implemented in the Linux kernel networking subsystem handling synchronization. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.
(CVE-2017-1000111, Important)

* 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, Important)

* A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto(). (CVE-2016-8399, Moderate)

* Kernel memory corruption due to a buffer overflow was found in brcmf_cfg80211_mgmt_tx() function in Linux kernels from v3.9-rc1 to v4.13-rc1. The vulnerability can be triggered by sending a crafted NL80211_CMD_FRAME packet via netlink. This flaw is unlikely to be triggered remotely as certain userspace code is needed for this. An unprivileged local user could use this flaw 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 unlikely. (CVE-2017-7541, Moderate)

* An integer overflow vulnerability in ip6_find_1stfragopt() function was found. A local attacker that has privileges (of CAP_NET_RAW) to open raw socket can cause an infinite loop inside the ip6_find_1stfragopt() function. (CVE-2017-7542, Moderate)

* A kernel data leak due to an out-of-bound read was found in the Linux kernel in inet_diag_msg_sctp{,l}addr_fill() and sctp_get_sctp_info() functions present since version 4.7-rc1 through version 4.13. A data leak happens when these functions fill in sockaddr data structures used to export socket's diagnostic information. As a result, up to 100 bytes of the slab data could be leaked to a userspace. (CVE-2017-7558, Moderate)

* The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use-after-free) which may lead to memory corruption or other unspecified other impact. (CVE-2017-11176, Moderate)

* A divide-by-zero vulnerability was found in the __tcp_select_window function in the Linux kernel. This can result in a kernel panic causing a local denial of service. (CVE-2017-14106, Moderate)
