    NASL id SUSE_SU-2017-1853-1.NASL
    description The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.74 to receive various security and bugfixes. The following security bugs were fixed : - 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-2017-7346: The vmw_gb_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate certain levels data, which allowed local users to cause a denial of service (system hang) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031796). - 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-2017-9076: 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-2017-8924: 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. (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. (bsc#1038981) - 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-2017-9150: The do_check function in kernel/bpf/verifier.c in the Linux kernel did not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allowed local users to obtain sensitive address information via crafted bpf system calls (bnc#1040279). - CVE-2017-7618: crypto/ahash.c in the Linux kernel allowed attackers to cause a denial of service (API operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue (bnc#1033340). - 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).

    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-2016-2188 Ralf Spenneberg of OpenSource Security reported that the iowarrior device driver did not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash). CVE-2016-9604 It was discovered that the keyring subsystem allowed a process to set a special internal keyring as its session keyring. The security impact in this version of the kernel is unknown. CVE-2016-10200 Baozeng Ding and Andrey Konovalov reported a race condition in the L2TP implementation which could corrupt its table of bound sockets. A local user could use this to cause a denial of service (crash) or possibly for privilege escalation. CVE-2017-2647 / CVE-2017-6951 idl3r reported that the keyring subsystem would allow a process to search for 'dead' keys, causing a NULL pointer dereference. A local user could use this to cause a denial of service (crash). CVE-2017-2671 Daniel Jiang discovered a race condition in the ping socket implementation. A local user with access to ping sockets could use this to cause a denial of service (crash) or possibly for privilege escalation. This feature is not accessible to any users by default. CVE-2017-5967 Xing Gao reported that the /proc/timer_list file showed information about all processes, not considering PID namespaces. If timer debugging was enabled by a privileged user, this leaked information to processes contained in PID namespaces. 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-2017-7184 Chaitin Security Research Lab discovered that the net xfrm subsystem did not sufficiently validate replay state parameters, allowing a heap buffer overflow. This can be used by a local user with the CAP_NET_ADMIN capability for privilege escalation. CVE-2017-7261 Vladis Dronov and Murray McAllister reported that the vmwgfx driver did not sufficiently validate rendering surface parameters. In a VMware guest, this can be used by a local user to cause a denial of service (crash). CVE-2017-7273 Benoit Camredon reported that the hid-cypress driver did not sufficiently validate HID reports. This possibly allowed a physically present user with a specially designed USB device to cause a denial of service (crash). CVE-2017-7294 Li Qiang reported that the vmwgfx driver did not sufficiently validate rendering surface parameters. In a VMware guest, this can be used by a local user to cause a denial of service (crash) or possibly for privilege escalation. CVE-2017-7308 Andrey Konovalov reported that the packet socket (AF_PACKET) implementation did not sufficiently validate buffer parameters. This can be used by a local user with the CAP_NET_RAW capability for privilege escalation. CVE-2017-7472 Eric Biggers reported that the keyring subsystem allowed a thread to create new thread keyrings repeatedly, causing a memory leak. This can be used by a local user to cause a denial of service (memory exhaustion). CVE-2017-7616 Chris Salls reported an information leak in the 32-bit big-endian compatibility implementations of set_mempolicy() and mbind(). This does not affect any architecture supported in Debian 7 LTS. CVE-2017-7618 Sabrina Dubroca reported that the cryptographic hash subsystem does not correctly handle submission of unaligned data to a device that is already busy, resulting in infinite recursion. On some systems this can be used by local users to cause a denial of service (crash). For Debian 7 'Wheezy', these problems have been fixed in version 3.2.88-1. This version also includes bug fixes from upstream version 3.2.88, and fixes some older security issues in the keyring, packet socket and cryptographic hash subsystems that do not have CVE IDs. For Debian 8 'Jessie', most of these problems have been fixed in version 3.16.43-1 which will be part of the next point release. We recommend that you upgrade your linux packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that the netfilter netlink implementation in the Linux kernel did not properly validate batch messages. A local attacker with the CAP_NET_ADMIN capability could use this to expose sensitive information or cause a denial of service. (CVE-2016-7917) Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build() function in the Linux kernel. A local attacker could use to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. (CVE-2016-8632) It was discovered that the keyring implementation in the Linux kernel in some situations did not prevent special internal keyrings from being joined by userspace keyrings. A privileged local attacker could use this to bypass module verification. (CVE-2016-9604) Dmitry Vyukov discovered that KVM implementation in the Linux kernel improperly emulated the VMXON instruction. A local attacker in a guest OS could use this to cause a denial of service (memory consumption) in the host OS. (CVE-2017-2596) Daniel Jiang discovered that a race condition existed in the ipv4 ping socket implementation in the Linux kernel. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2017-2671) Di Shen discovered that a race condition existed in the perf subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly gain administrative privileges. (CVE-2017-6001) Eric Biggers discovered a memory leak in the keyring implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2017-7472) Sabrina Dubroca discovered that the asynchronous cryptographic hash (ahash) implementation in the Linux kernel did not properly handle a full request queue. A local attacker could use this to cause a denial of service (infinite recursion). (CVE-2017-7618) Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly handle certain long RPC replies. A remote attacker could use this to cause a denial of service (system crash). (CVE-2017-7645) Tommi Rantala and Brad Spengler discovered that the memory manager in the Linux kernel did not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism. A local attacker with access to /dev/mem could use this to expose sensitive information or possibly execute arbitrary code. (CVE-2017-7889) Tuomas Haanpaa and Ari Kauppi discovered that the NFSv2 and NFSv3 server implementations in the Linux kernel did not properly check for the end of buffer. A remote attacker could use this to craft requests that cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7895) It was discovered that a use-after-free vulnerability existed in the device driver for XCeive xc2028/xc3028 tuners in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-7913) Vlad Tsyrklevich discovered an integer overflow vulnerability in the VFIO PCI driver for the Linux kernel. A local attacker with access to a vfio PCI device file could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2016-9083, CVE-2016-9084).

    NASL id OPENSUSE-2017-532.NASL
    description The openSUSE Leap 42.2 kernel was updated to 4.4.62 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-7618: crypto/ahash.c in the Linux kernel allowed attackers to cause a denial of service (API operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue (bnc#1033340). - CVE-2016-4997: The compat IPT_SO_SET_REPLACE and IP6T_SO_SET_REPLACE setsockopt implementations in the netfilter subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption) by leveraging in-container root access to provide a crafted offset value that triggers an unintended decrement (bnc#986362). - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary (bnc#986365). - 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-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux kernel was 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-2017-7308: 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).

    description The openSUSE Leap 42.1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-7618: crypto/ahash.c in the Linux kernel allowed attackers to cause a denial of service (API operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue (bnc#1033340). - CVE-2016-10318: A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel allowed a user to assign an encryption policy to a directory owned by a different user, potentially creating a denial of service (bnc#1032435). - 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-2017-7308: 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 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-2017-7294: 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). The following non-security bugs were fixed : - ata: ahci_xgene: free structure returned by acpi_get_object_info() (bsc#1033518). - doc/README.SUSE: update links to KMP manual - ext4: do not perform data journaling when data is encrypted (bsc#1012876). - ext4: fix use-after-iput when fscrypt contexts are inconsistent (bsc#1012829). - ext4: mark inode dirty after converting inline directory (bsc#1012876). - ext4: reject inodes with negative size (bsc#1012876). - fs, seqfile: always allow oom killer (bsc#1012876). - ipv6: make ECMP route replacement less greedy (bsc#930399). - l2tp: hold tunnel socket when handling control frames in l2tp_ip and l2tp_ip6 (bsc#1028415). - mm: filemap: do not plant shadow entries without radix tree node (bsc#1012876). - netfilter: allow logging from non-init namespaces (bsc#970083). - nfsd4: minor NFSv2/v3 write decoding cleanup (bsc#1034670 CVE#2017-7645). - nfsd: check for oversized NFSv2/v3 arguments (bsc#1034670 CVE#2017-7645). - nfsd: stricter decoding of write-like NFSv2/v3 ops (bsc#1034670 CVE#2017-7645).

    description Infinite recursion in ahash.c by triggering EBUSY on a full queue : A vulnerability was found in crypto/ahash.c in the Linux kernel which allows attackers to cause a denial of service (API operation calling its own callback, and infinite recursion) by triggering EBUSY on a full queue.(CVE-2017-7618) Time subsystem allows local users to discover real PID values : The time subsystem in the Linux kernel, when CONFIG_TIMER_STATS is enabled, allows local users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the __timer_stats_timer_set_start_info function in kernel/time/timer.c.(CVE-2017-5967) Stack-based buffer overflow in sg_ioctl function : The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impacts 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. (CVE-2017-7187) Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c : Incorrect error handling in the set_mempolicy() and mbind() compat syscalls in mm/mempolicy.c; in the Linux kernel allows local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. (CVE-2017-7616) Race condition in Link Layer Control : A race condition leading to a NULL pointer dereference was found in the Linux kernel's Link Layer Control implementation. A local attacker with access to ping sockets could use this flaw to crash the system. (CVE-2017-2671) Overflow in check for priv area size : It was found that the packet_set_ring() function of the Linux kernel's networking implementation did not properly validate certain block-size data. A local attacker with CAP_NET_RAW capability could use this flaw to trigger a buffer overflow, resulting in the crash of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-7308)
