Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

This can be exploited by local users to cause a subsequent denial of service.(CVE-2017-18204i1/4%0 - The vmw_gb_surface_define_ioctl function (accessible via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.11.4 defines a backup_handle variable but does not give it an initial value. If one attempts to create a GB surface, with a previously allocated DMA buffer to be used as a backup buffer, the backup_handle variable does not get written to and is then later returned to user space, allowing local users to obtain sensitive information from uninitialized kernel memory via a crafted ioctl call.(CVE-2017-9605i1/4%0 - Use-after-free vulnerability in the nfqnl_zcopy function in net/netfilter/nfnetlink_queue_core.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation. NOTE: the affected code was moved to the skb_zerocopy function in net/core/skbuff.c before the vulnerability was announced.(CVE-2014-2568i1/4%0 - It was found that the Linux kernel's ISO file system implementation did not correctly limit the traversal of Rock Ridge extension Continuation Entries (CE). An attacker with physical access to the system could use this flaw to trigger an infinite loop in the kernel, resulting in a denial of service.(CVE-2014-9420i1/4%0 - An integer overflow vulnerability was found in the ring_buffer_resize() calculations in which a privileged user can adjust the size of the ringbuffer message size. These calculations can create an issue where the kernel memory allocator will not allocate the correct count of pages yet expect them to be usable. This can lead to the ftrace() output to appear to corrupt kernel memory and possibly be used for privileged escalation or more likely kernel panic.(CVE-2016-9754i1/4%0 - A symlink size validation was missing in Linux kernels built with UDF file system (CONFIG_UDF_FS) support, allowing the corruption of kernel memory. An attacker able to mount a corrupted/malicious UDF file system image could cause the kernel to crash.(CVE-2014-9730i1/4%0 - In was found that in the Linux kernel, in vmw_surface_define_ioctl() function in 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a 'num_sizes' parameter is assigned a user-controlled value which is not checked if it is zero. This is used in a call to kmalloc() and later leads to dereferencing ZERO_SIZE_PTR, which in turn leads to a GPF and possibly to a kernel panic.(CVE-2017-7261i1/4%0 - A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash.(CVE-2014-9529i1/4%0 - A flaw was found in the Linux kernel's implementation of i8042 serial ports. An attacker could cause a kernel panic if they are able to add and remove devices as the module is loaded.(CVE-2017-18079i1/4%0 - drivers/hid/hid-pl.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_PANTHERLORD is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) via a crafted device.(CVE-2013-2892i1/4%0 - The __clear_user function in arch/arm64/lib/clear_user.S in the Linux kernel before 3.17.4 on the ARM64 platform allows local users to cause a denial of service (system crash) by reading one byte beyond a /dev/zero page boundary.(CVE-2014-7843i1/4%0 - A divide-by-zero vulnerability was found in a way the kernel processes TCP connections. The error can occur if a connection starts another cwnd reduction phase by setting tp-i1/4zprior_cwnd to the current cwnd (0) in tcp_init_cwnd_reduction(). A remote, unauthenticated attacker could use this flaw to crash the kernel (denial of service).(CVE-2016-2070i1/4%0 - The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions.(CVE-2016-2383i1/4%0 - System using the infiniband support module ib_srpt were vulnerable to a denial of service by system crash by a local attacker who is able to abort writes to a device using this initiator.(CVE-2016-6327i1/4%0 - A security flaw was found in the Linux kernel in the mark_source_chains() function in 'net/ipv4/netfilter/ip_tables.c'. It is possible for a user-supplied 'ipt_entry' structure to have a large 'next_offset' field. This field is not bounds checked prior to writing to a counter value at the supplied offset.(CVE-2016-3134i1/4%0 - An out-of-bounds access issue was discovered in yurex_read() in drivers/usb/misc/yurex.c in the Linux kernel. A local attacker could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges.(CVE-2018-16276i1/4%0 - drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux kernel before 4.5.3 allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a crafted number of planes in a VIDIOC_DQBUF ioctl call.(CVE-2016-4568i1/4%0 - The usb_serial_console_disconnect function in drivers/usb/serial/console.c in the Linux kernel, before 4.13.8, allows local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted USB device, related to disconnection and failed setup.(CVE-2017-16525i1/4%0 - The Linux kernel is vulnerable to a NULL pointer dereference in the ext4/xattr.c:ext4_xattr_inode_hash() function. An attacker could trick a legitimate user or a privileged attacker could exploit this to cause a NULL pointer dereference with a crafted ext4 image.

CVE-2012-6704, CVE-2016-9793 Eric Dumazet found that a local user with CAP_NET_ADMIN capability could set a socket's buffer size to be negative, leading to a denial of service or other security impact. Additionally, in kernel versions prior to 3.5, any user could do this if sysctl net.core.rmem_max was changed to a very large value. CVE-2015-1350 / #770492 Ben Harris reported that local users could remove set-capability attributes from any file visible to them, allowing a denial of service. CVE-2015-8962 Calvin Owens fouund that removing a SCSI device while it was being accessed through the SCSI generic (sg) driver led to a double- free, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could be exploited by local users with permision to access a SCSI device node. CVE-2015-8963 Sasha Levin reported that hot-unplugging a CPU resulted in a use-after-free by the performance events (perf) subsystem, possibly causing a denial of service (crash or memory corruption) or privilege escalation. This could by exploited by any local user. CVE-2015-8964 It was found that the terminal/serial (tty) subsystem did not reliably reset the terminal buffer state when the terminal line discipline was changed. This could allow a local user with access to a terminal device to read sensitive information from kernel memory. CVE-2016-7097 Jan Kara found that changing the POSIX ACL of a file 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-2016-7910 Vegard Nossum discovered that a memory allocation failure while handling a read of /proc/diskstats or /proc/partitions could lead to a use-after-free, possibly causing a denial of service (crash or memory corruption) or privilege escalation. CVE-2016-7911 Dmitry Vyukov reported that a race between ioprio_get() and ioprio_set() system calls could result in a use-after-free, possibly causing a denial of service (crash) or leaking sensitive information. CVE-2016-7915 Benjamin Tissoires found that HID devices could trigger an out-of- bounds memory access in the HID core. A physically present user could possibly use this for denial of service (crash) or to leak sensitive information. CVE-2016-8399 Qidan He reported that the IPv4 ping socket implementation did not validate the length of packets to be sent. A user with permisson to use ping sockets could cause an out-of-bounds read, possibly resulting in a denial of service or information leak. However, on Debian systems no users have permission to create ping sockets by default. CVE-2016-8633 Eyal Itkin reported that the IP-over-Firewire driver (firewire-net) did not validate the offset or length in link-layer fragmentation headers. This allowed a remote system connected by Firewire to write to memory after a packet buffer, leading to a denial of service (crash) or remote code execution. CVE-2016-8645 Marco Grassi reported that if a socket filter (BPF program) attached to a TCP socket truncates or removes the TCP header, this could cause a denial of service (crash). This was exploitable by any local user. CVE-2016-8655 Philip Pettersson found that the implementation of packet sockets (AF_PACKET family) had a race condition between enabling a transmit ring buffer and changing the version of buffers used, which could result in a use-after-free. A local user with the CAP_NET_ADMIN capability could exploit this for privilege escalation. CVE-2016-9178 Al Viro found that a failure to read data from user memory might lead to a information leak on the x86 architecture (amd64 or i386). CVE-2016-9555 Andrey Konovalov reported that the SCTP implementation does not validate 'out of the blue' packet chunk lengths early enough. A remote system able could use this to cause a denial of service (crash) or other security impact for systems using SCTP. CVE-2016-9576, CVE-2016-10088 Dmitry Vyukov reported that using splice() with the SCSI generic driver led to kernel memory corruption. Local users with permision to access a SCSI device node could exploit this for privilege escalation. CVE-2016-9756 Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or i386) did not correctly handle the failure of certain instructions that require software emulation on older processors. This could be exploited by guest systems to leak sensitive information or for denial of service (log spam). CVE-2016-9794 Baozeng Ding reported a race condition in the ALSA (sound) subsystem that could result in a use-after-free. Local users with access to a PCM sound device could exploit this for denial of service (crash or memory corruption) or other security impact. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.84-1. This version also includes bug fixes from upstream version 3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122. Finally, this version adds the option to mitigate security issues in the performance events (perf) subsystem by disabling use by unprivileged users. This can be done by setting sysctl kernel.perf_event_paranoid=3. For Debian 8 'Jessie', these problems have been fixed in version 3.16.39-1 which will be included in the next point release (8.6).

A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841, Important) * Several Moderate and Low impact security issues were found in the Linux kernel. Space precludes documenting each of these issues in this advisory. Refer to the CVE links in the References section for a description of each of these vulnerabilities.

Enhancements and bugfixes over the previous fixes have been added to this kernel. - CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might have allowed local users to cause a denial of service by triggering an attempted use of the -INT_MIN value (bnc#1089608). - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536). - CVE-2018-7566: There was a buffer overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user (bnc#1083483). - CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem allowed attackers to gain privileges via unspecified vectors (bnc#1088260). - CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious NCPFS servers to crash the kernel or execute code (bnc#1086162). - CVE-2017-13166: An elevation of privilege vulnerability in the kernel v4l2 video driver. (bnc#1072865). - CVE-2017-18203: The dm_get_from_kobject function in drivers/md/dm.c allowed local users to cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and removal of DM devices (bnc#1083242). - CVE-2017-16911: The vhci_hcd driver allowed allows local attackers to disclose kernel memory addresses. Successful exploitation requires that a USB device is attached over IP (bnc#1078674). - CVE-2017-18208: The madvise_willneed function in mm/madvise.c local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494). - CVE-2017-16644: The hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c allowed local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067118). - CVE-2018-6927: The futex_requeue function in kernel/futex.c in the Linux kernel might allow attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a negative wake or requeue value (bnc#1080757). - CVE-2017-16914: The 'stub_send_ret_submit()' function (drivers/usb/usbip/stub_tx.c) allowed attackers to cause a denial of service (NULL pointer dereference) via a specially crafted USB over IP packet (bnc#1078669). - CVE-2016-7915: The hid_input_field function in drivers/hid/hid-core.c allowed physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device, as demonstrated by a Logitech DJ receiver (bnc#1010470). - CVE-2015-5156: The virtnet_probe function in drivers/net/virtio_net.c attempted to support a FRAGLIST feature without proper memory allocation, which allowed guest OS users to cause a denial of service (buffer overflow and memory corruption) via a crafted sequence of fragmented packets (bnc#940776). - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user functions in block/bio.c did unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition (bnc#1062568). - CVE-2017-16912: The 'get_pipe()' function (drivers/usb/usbip/stub_rx.c) allowed attackers to cause a denial of service (out-of-bounds read) via a specially crafted USB over IP packet (bnc#1078673). - CVE-2017-16913: The 'stub_recv_cmd_submit()' function (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT packets allowed attackers to cause a denial of service (arbitrary memory allocation) via a specially crafted USB over IP packet (bnc#1078672).

script_set_attribute(attribute:"description", value: "According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The hid_input_field function in drivers/hid/hid-core.c in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device, as demonstrated by a Logitech DJ receiver.(CVE-2016-7915) - In the Linux kernel through 4.14.13, drivers/block/loop.c mishandles lo_release serialization, which allows attackers to cause a denial of service (__lock_acquire use-after-free) or possibly have unspecified other impact.(CVE-2018-5344) - In the Linux kernel through 4.14.13, the rds_cmsg_atomic() function in 'net/rds/rdma.c' mishandles cases where page pinning fails or an invalid address is supplied by a user. This can lead to a NULL pointer dereference in rds_atomic_free_op() and thus to a system panic.(CVE-2018-5333) - In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2018-5332) - A flaw was found in the upstream kernel Skcipher component. This vulnerability affects the skcipher_recvmsg function of the component Skcipher. The manipulation with an unknown input leads to a privilege escalation vulnerability.(CVE-2017-13215) - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.(CVE-2017-18017) - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.(CVE-2017-17805) - The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.(CVE-2017-17806) - he KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task's 'default request-key keyring' via the request_key() system call, allowing a local user to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.(CVE-2017-17807) - The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic.(CVE-2017-1000407) - The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939) - The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state.(CVE-2017-8824) - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.(CVE-2017-17448) - Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allows attackers to gain privileges via unspecified vectors.(CVE-2017-0861) - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-17558) - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.(CVE-2017-17449) - net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.(CVE-2017-17450) - The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.(CVE-2017-15868) - The einj_error_inject function in drivers/acpi/apei/einj.c in the Linux kernel allows local users to simulate hardware errors and consequently cause a denial of service by leveraging failure to disable APEI error injection through EINJ when securelevel is set.(CVE-2016-3695) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.(CVE-2016-7117) - A heap-buffer overflow vulnerability was found in the arcmsr_iop_message_xfer() function in 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux kernel through 4.8.2. The function does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can potentially cause kernel heap corruption and arbitrary kernel code execution.(CVE-2016-7425) - A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.(CVE-2016-7910) - A use-after-free vulnerability in sys_ioprio_get() was found due to get_task_ioprio() accessing the task-i1/4zio_context without holding the task lock and could potentially race with exit_io_context(), leading to a use-after-free.(CVE-2016-7911) - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2016-7913) - The assoc_array_insert_into_terminal_node() function in 'lib/assoc_array.c' in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures.(CVE-2016-7914) - The hid_input_field() function in 'drivers/hid/hid-core.c' in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device.(CVE-2016-7915) - Race condition in the environ_read() function in 'fs/proc/base.c' in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a '/proc/*/environ' file during a process-setup time interval in which environment-variable copying is incomplete.(CVE-2016-7916) - 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) - Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support is vulnerable to a null pointer dereference flaw. It could occur on x86 platform, when emulating an undefined instruction. An attacker could use this flaw to crash the host kernel resulting in DoS.(CVE-2016-8630) - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633) - It was discovered that the Linux kernel since 3.6-rc1 with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG() statement in tcp_collapse() function after making a number of certain syscalls leading to a possible system crash.(CVE-2016-8645) - A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set.(CVE-2016-8646) - 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) - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. 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-2016-8655) - A flaw was found in the way the Linux kernel's networking subsystem handled offloaded packets with multiple layers of encapsulation in the GRO (Generic Receive Offload) code path. A remote attacker could use this flaw to trigger unbounded recursion in the kernel that could lead to stack corruption, resulting in a system crash.(CVE-2016-8666) - A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution.(CVE-2016-9083) - The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine.(CVE-2016-9084) - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.(CVE-2016-9555) - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.(CVE-2016-9576) - Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to an uncaught exception issue. It could occur if an L2 guest was to throw an exception which is not handled by an L1 guest.(CVE-2016-9588) - It was discovered that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.(CVE-2016-9604) - A flaw was found in the Linux kernel's implementation of XFS file attributes. Two memory leaks were detected in xfs_attr_shortform_list and xfs_attr3_leaf_list_int when running a docker container backed by xfs/overlay2. A dedicated attacker could possible exhaust all memory and create a denial of service situation.(CVE-2016-9685) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

The following security bugs were fixed : - CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bnc#1085107). - CVE-2017-18221: The __munlock_pagevec function allowed local users to cause a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system calls (bnc#1084323). - CVE-2018-1066: Prevent NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response was mishandled during session recovery (bnc#1083640). - CVE-2017-13166: Prevent elevation of privilege vulnerability in the kernel v4l2 video driver (bnc#1072865). - CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose kernel memory addresses. Successful exploitation required that a USB device was attached over IP (bnc#1078674). - CVE-2017-15299: The KEYS subsystem mishandled use of add_key for a key that already exists but is uninstantiated, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted system call (bnc#1063416). - CVE-2017-18208: The madvise_willneed function kernel allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494). - CVE-2018-7566: The ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty.

The bio_add_pc_page function merged them into one, but the page reference was never dropped. This caused a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition (bnc#1062568). - CVE-2017-16912: The 'get_pipe()' function allowed attackers to cause a denial of service (out-of-bounds read) via a specially crafted USB over IP packet (bnc#1078673). - CVE-2017-16913: The 'stub_recv_cmd_submit()' function when handling CMD_SUBMIT packets allowed attackers to cause a denial of service (arbitrary memory allocation) via a specially crafted USB over IP packet (bnc#1078672). - CVE-2018-5332: The rds_message_alloc_sgs() function did not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621). - CVE-2018-5333: The rds_cmsg_atomic function in net/rds/rdma.c mishandled cases where page pinning fails or an invalid address is supplied, leading to an rds_atomic_free_op NULL pointer dereference (bnc#1075617). - CVE-2017-18017: The tcpmss_mangle_packet function allowed remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action (bnc#1074488). The update package also includes non-security fixes. See advisory for details.
