  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

    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 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2016-10208 Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation. CVE-2017-8824 Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for 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 CVE-2017-8831 Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation. CVE-2017-12190 Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation. CVE-2017-13080 A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'. Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation. CVE-2017-14051 'shqking' reported that the qla2xxx SCSI host driver did not correctly validate I/O to the 'optrom' sysfs attribute of the devices it creates. This is unlikely to have any security impact. CVE-2017-15115 Vladis Dronov reported that the SCTP implementation did not correctly handle 'peel-off' of an association to another net namespace. This leads to a use-after-free, which a local user can exploit for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the sctp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-sctp.conf install sctp false CVE-2017-15265 Michael23 Yu reported a race condition in the ALSA sequencer subsystem involving creation and deletion of ports, which could lead to a use-after-free. A local user with access to an ALSA sequencer device can use this for denial of service (crash or data loss) or possibly for privilege escalation. CVE-2017-15299 Eric Biggers discovered that the KEYS subsystem did not correctly handle update of an uninstantiated key, leading to a null dereference. A local user can use this for denial of service (crash). CVE-2017-15649 'nixioaming' reported a race condition in the packet socket (AF_PACKET) implementation involving rebinding to a fanout group, which could lead to a use-after-free. A local user with the CAP_NET_RAW capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. CVE-2017-15868 Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. CVE-2017-16525 Andrey Konovalov reported that the USB serial console implementation did not correctly handle disconnection of unusual serial devices, leading to a use-after-free. A similar issue was found in the case where setup of a serial console fails. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation. CVE-2017-16527 Andrey Konovalov reported that the USB sound mixer driver did not correctly cancel I/O in case it failed to probe a device, which could lead to a use-after-free. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation. CVE-2017-16529 Andrey Konovalov reported that the USB sound driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash). CVE-2017-16531 Andrey Konovalov reported that the USB core did not validate IAD lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash). CVE-2017-16532 Andrey Konovalov reported that the USB test driver did not correctly handle devices with specific combinations of endpoints. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). CVE-2017-16533 Andrey Konovalov reported that the USB HID driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash). CVE-2017-16535 Andrey Konovalov reported that the USB core did not validate BOS descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash). CVE-2017-16536 Andrey Konovalov reported that the cx231xx video capture driver did not fully validate the device endpoint configuration, which could lead to a null dereference. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). CVE-2017-16537 Andrey Konovalov reported that the imon RC driver did not fully validate the device interface configuration, which could lead to a null dereference. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). CVE-2017-16643 Andrey Konovalov reported that the gtco tablet driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash). CVE-2017-16649 Bjørn Mork found that the cdc_ether network driver did not validate the device's maximum segment size, potentially leading to a division by zero. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). CVE-2017-16939 Mohamed Ghannam reported (through Beyond Security's SecuriTeam Secure Disclosure program) that the IPsec (xfrm) implementation did not correctly handle some failure cases when dumping policy information through netlink. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. CVE-2017-1000407 Andrew Honig reported that the KVM implementation for Intel processors allowed direct access to host I/O port 0x80, which is not generally safe. On some systems this allows a guest VM to cause a denial of service (crash) of the host. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.96-2. This version also includes bug fixes from upstream versions up to and including 3.2.96. It also fixes some regressions caused by the fix for CVE-2017-1000364, which was included in DLA-993-1. We recommend that you upgrade your linux packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

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. 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.
