    description Security Fix(es) : - A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074, Important) - It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system. (CVE-2017-2634, Moderate) Important: This update disables the DCCP kernel module at load time by using the kernel module blacklist method. The module is disabled in an attempt to reduce further exposure to additional issues.

    description The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.58 to receive various security and bugfixes. Notable new/improved features : - Improved support for Hyper-V - Support for Matrox G200eH3 - Support for tcp_westwood The following security bugs were fixed : - 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-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579). - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440). - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052). - 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). - CVE-2017-7374: Use-after-free vulnerability in fs/crypto/ in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference) or possibly gain privileges by revoking keyring keys being used for ext4, f2fs, or ubifs encryption, causing cryptographic transform objects to be freed prematurely (bnc#1032006). - 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-2017-6345: The LLC subsystem in the Linux kernel did not ensure that a certain destructor exists in required circumstances, which allowed local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls (bnc#1027190). - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that made PACKET_FANOUT setsockopt system calls (bnc#1027189). - 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-2017-6214: 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-2016-2117: The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly enables scatter/gather I/O, which allowed remote attackers to obtain sensitive information from kernel memory by reading packet data (bnc#968697). - CVE-2017-6347: The ip_cmsg_recv_checksum function in net/ipv4/ip_sockglue.c in the Linux kernel had incorrect expectations about skb data layout, which allowed local users to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted system calls, as demonstrated by use of the MSG_MORE flag in conjunction with loopback UDP transmission (bnc#1027179). - CVE-2016-9191: The cgroup offline implementation in the Linux kernel mishandled certain drain operations, which allowed local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application (bnc#1008842). - CVE-2017-2596: The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel improperly emulated the VMXON instruction, which allowed KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references (bnc#1022785). - 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). The update package also includes non-security fixes. See advisory for details.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts. CVE-2014-9888 Russell King found that on ARM systems, memory allocated for DMA buffers was mapped with executable permission. This made it easier to exploit other vulnerabilities in the kernel. CVE-2014-9895 Dan Carpenter found that the MEDIA_IOC_ENUM_LINKS ioctl on media devices resulted in an information leak. CVE-2016-6786 / CVE-2016-6787 It was discovered that the performance events subsystem does not properly manage locks during certain migrations, allowing a local attacker to escalate privileges. This can be mitigated by disabling unprivileged use of performance events: sysctl kernel.perf_event_paranoid=3 CVE-2016-8405 Peter Pi of Trend Micro discovered that the frame buffer video subsystem does not properly check bounds while copying color maps to userspace, causing a heap buffer out-of-bounds read, leading to information disclosure. CVE-2017-5549 It was discovered that the KLSI KL5KUSB105 serial USB device driver could log the contents of uninitialised kernel memory, resulting in an information leak. CVE-2017-6001 Di Shen discovered a race condition between concurrent calls to the performance events subsystem, allowing a local attacker to escalate privileges. This flaw exists because of an incomplete fix of CVE-2016-6786. This can be mitigated by disabling unprivileged use of performance events: sysctl kernel.perf_event_paranoid=3 CVE-2017-6074 Andrey Konovalov discovered a use-after-free vulnerability in the DCCP networking code, which could result in denial of service or local privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false For Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-2. For Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1+deb8u1 or earlier. We recommend that you upgrade your linux packages.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2017-0501.NASL
    description An update for kernel is now available for Red Hat Enterprise Linux 7.2 Extended Update Support. 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) : * A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074, Important) Red Hat would like to thank Andrey Konovalov (Google) for reporting this issue. Bug Fix(es) : * Previously, running the 'ethtool -S' command to get the statistics of a Brocade Network Adapter (BNA) sometimes caused a kernel panic. This update applies a set of patches to the bna driver, and the kernel panic no longer occurs in the described scenario. (BZ#1408130) * Use of a multi-threaded workload with high memory mappings sometimes caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer panics in the described scenario. (BZ#1410865) * Previously, the kernel was sending a Transmission Control Protocol (TCP) window which had a size of zero for a socket with an empty receive queue. Consequently, the TCP session became unresponsive. This update fixes the ibmveth driver to set correct values of the gso_size and gso_type variables and to calculate the value of the gso_segs variable for large packets. As a result, the TCP session no longer hangs in the described scenario. (BZ# 1411381) * Previously, booting a kdump kernel in some cases failed with this error : Kernel panic - not syncing: Watchdog detected hard LOCKUP on CPU 0. This update ensures that the hpet timer software counters, including hpet_default_delta and hpet_t1_cmp, are initialized before an interrupt request is registered, and the kdump kernel now boots without the mentioned error message. (BZ#1404183) * When one of the drives became unresponsive, all other drives intermittently hung, because the megaraid_sas driver incorrectly sent a reset request to the PowerEdge RAID Controller (PERC). This update fixes megaraid_sas, and thus the hang of one drive no longer leads to intermittent loss of access to all drives on the system. (BZ#1398174)

    description A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074) A vulnerability was found in the Linux kernel. When file permissions are modified via chmod and the user is not in the owning group or capable of CAP_FSETID, the setgid bit is cleared in inode_change_ok(). Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way; this allows to bypass the check in chmod. (CVE-2016-7097) A vulnerability was found in the Linux kernel in 'tmpfs' file system. When file permissions are modified via 'chmod' and the user is not in the owning group or capable of CAP_FSETID, the setgid bit is cleared in inode_change_ok(). Setting a POSIX ACL via 'setxattr' sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in a similar way; this allows to bypass the check in 'chmod'. (CVE-2017-5551) An issue was found in the Linux kernel ipv6 implementation of GRE tunnels which allows a remote attacker to trigger an out-of-bounds access. (CVE-2017-5897) It was discovered that an application may trigger a BUG_ON in sctp_wait_for_sndbuf if the socket tx buffer is full, a thread is waiting on it to queue more data, and meanwhile another thread peels off the association being used by the first thread. (CVE-2017-5986) A vulnerability was found in the Linux kernel where having malicious IP options present would cause the ipv4_pktinfo_prepare() function to drop/free the dst. This could result in a system crash or possible privilege escalation. (CVE-2017-5970) A flaw was found in the Linux kernel's handling of packets with the URG flag. Applications using the splice() and tcp_splice_read() functionality can allow a remote attacker to force the kernel to enter a condition in which it can loop indefinitely. (CVE-2017-6214) (Updated on 2017-03-21: CVE-2017-5970 was fixed in this release but was previously not part of this errata.) (Updated on 2017-06-07: CVE-2017-6214 was fixed in this release but was previously not part of this errata.)

This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS. It was discovered that a use-after-free vulnerability existed in the block device layer of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-7910) Dmitry Vyukov discovered a use-after-free vulnerability in the sys_ioprio_get() function in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2016-7911) Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. (CVE-2017-6074).

(bsc#1030593) - CVE-2016-9604: This fixes handling of keyrings starting with '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to manipulate privileged keyrings (bsc#1035576) - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. (bnc#1033336). - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (bsc#1034670). - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579) - 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-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440) - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052) -

    NASL id SUSE_SU-2017-1247-1.NASL
    description The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-1350: The VFS subsystem in the Linux kernel provided an incomplete set of requirements for setattr operations that underspecifies 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-2016-2117: The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly enabled scatter/gather I/O, which allowed remote attackers to obtain sensitive information from kernel memory by reading packet data (bnc#968697). - CVE-2016-3070: The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel improperly interacted with mm/migrate.c, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move (bnc#979215). - CVE-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212). - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077). - CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanages the #BP and #OF exceptions, which allowed guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest (bnc#1015703). - CVE-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel did not properly restrict execute access, which made it easier for local users to bypass intended SELinux W^X policy restrictions, and consequently gain privileges, via an io_setup system call (bnc#1023992). - 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-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the Linux kernel did not properly validate meta block groups, which allowed physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image (bnc#1023377). - CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux kernel is too late in obtaining a certain lock and consequently cannot 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-2017-5897: The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allowed remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access (bnc#1023762). - 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 (bnc#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 (bnc#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-2017-6345: The LLC subsystem in the Linux kernel did not ensure that a certain destructor exists in required circumstances, which allowed local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls (bnc#1027190). - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux kernel allowed local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that made PACKET_FANOUT setsockopt system calls (bnc#1027189). - 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-2017-7187: 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). - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052). - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440). - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579). - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation (bnc#1033336). 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.

    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts. - CVE-2016-6786 / CVE-2016-6787 It was discovered that the performance events subsystem does not properly manage locks during certain migrations, allowing a local attacker to escalate privileges. This can be mitigated by disabling unprivileged use of performance events:sysctl kernel.perf_event_paranoid=3 - CVE-2016-8405 Peter Pi of Trend Micro discovered that the frame buffer video subsystem does not properly check bounds while copying color maps to userspace, causing a heap buffer out-of-bounds read, leading to information disclosure. - CVE-2016-9191 CAI Qian discovered that reference counting is not properly handled within proc_sys_readdir in the sysctl implementation, allowing a local denial of service (system hang) or possibly privilege escalation. - CVE-2017-2583 Xiaohan Zhang reported that KVM for amd64 does not correctly emulate loading of a null stack selector. This can be used by a user in a guest VM for denial of service (on an Intel CPU) or to escalate privileges within the VM (on an AMD CPU). - CVE-2017-2584 Dmitry Vyukov reported that KVM for x86 does not correctly emulate memory access by the SGDT and SIDT instructions, which can result in a use-after-free and information leak. - CVE-2017-2596 Dmitry Vyukov reported that KVM leaks page references when emulating a VMON for a nested hypervisor. This can be used by a privileged user in a guest VM for denial of service or possibly to gain privileges in the host. - CVE-2017-2618 It was discovered that an off-by-one in the handling of SELinux attributes in /proc/pid/attr could result in local denial of service. - CVE-2017-5549 It was discovered that the KLSI KL5KUSB105 serial USB device driver could log the contents of uninitialised kernel memory, resulting in an information leak. - CVE-2017-5551 Jan Kara found that changing the POSIX ACL of a file on tmpfs never cleared its set-group-ID flag, which should be done if the user changing it is not a member of the group-owner. In some cases, this would allow the user-owner of an executable to gain the privileges of the group-owner. - CVE-2017-5897 Andrey Konovalov discovered an out-of-bounds read flaw in the ip6gre_err function in the IPv6 networking code. - CVE-2017-5970 Andrey Konovalov discovered a denial-of-service flaw in the IPv4 networking code. This can be triggered by a local or remote attacker if a local UDP or raw socket has the IP_RETOPTS option enabled. - CVE-2017-6001 Di Shen discovered a race condition between concurrent calls to the performance events subsystem, allowing a local attacker to escalate privileges. This flaw exists because of an incomplete fix of CVE-2016-6786. This can be mitigated by disabling unprivileged use of performance events: sysctl kernel.perf_event_paranoid=3 - CVE-2017-6074 Andrey Konovalov discovered a use-after-free vulnerability in the DCCP networking code, which could result in denial of service or local privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it:echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

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-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es) : * A race condition flaw was found in the N_HLDC Linux kernel driver when accessing n_hdlc.tbuf list that can lead to double free. A local, unprivileged user able to set the HDLC line discipline on the tty device could use this flaw to increase their privileges on the system. (CVE-2017-2636, Important) * A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074, Important) * A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650, Moderate) * A flaw was found in the Linux kernel's implementation of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt() system call. Users with non-namespace CAP_NET_ADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative. This could adversely affect memory allocations and create situations where the system could crash or cause memory corruption. (CVE-2016-9793, Moderate) * A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory. (CVE-2017-2618, Moderate) Red Hat would like to thank Alexander Popov for reporting CVE-2017-2636; Andrey Konovalov (Google) for reporting CVE-2017-6074; and Ralf Spenneberg for reporting CVE-2016-8650.

    description The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. Notable new features : - Toleration of newer crypto hardware for z Systems - USB 2.0 Link power management for Haswell-ULT The following security bugs were fixed : - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579) - 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-2017-7184: 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-2017-5970: 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-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation (bsc#1033336). - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440) - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052) - 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) - 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-2017-5669: 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-2015-3288: mm/memory.c in the Linux kernel mishandled anonymous pages, which allowed local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero (bsc#979021). - 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-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212) - 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 (bnc#1027066) - 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-2017-6074: 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-2017-5986: 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-2015-8970: crypto/algif_skcipher.c in the Linux kernel did not verify that a setkey operation has been performed on an AF_ALG socket an accept system call is processed, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that does not supply a key, related to the lrw_crypt function in crypto/lrw.c (bsc#1008374). The update package also includes non-security fixes. See advisory for details.

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2017-0294.NASL
    description 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) : * A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074, Important)
