* linux-lts-xenial \- Linux hardware enablement kernel from Xenial for Trusty
USN-3084-1 fixed vulnerabilities in the Linux kernel for Ubuntu
16.04 LTS. This update provides the corresponding updates for the
Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for
Ubuntu 14.04 LTS.
Pengfei Wang discovered a race condition in the audit subsystem in the
Linux kernel. A local attacker could use this to corrupt audit logs or
disrupt system-call auditing. (CVE-2016-6136)
It was discovered that the powerpc and powerpc64 hypervisor-mode KVM
implementation in the Linux kernel for did not properly maintain state
about transactional memory. An unprivileged attacker in a guest could cause
a denial of service (CPU lockup) in the host OS. (CVE-2016-5412)
Pengfei Wang discovered a race condition in the Chrome OS embedded
controller device driver in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash). (CVE-2016-6156)

of Moderate. 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.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. (CVE-2016-6136, Moderate)\n\n* 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.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the '-o fsc' option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the '-o fsc' option. As a result, NFS no longer enables caching if the '-o fsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1397739)\n\n* When the 'punching hole' feature of the fallocate utility was used on an ext4 file system inode with extent depth of 1, the extent tree of the inode sometimes became corrupted. With this update, the underlying source code has been fixed, and extent tree corruption no longer occurs in the described situation.

of Moderate. 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.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. (CVE-2016-6136, Moderate)\n\n* 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.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es) :\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the '-o fsc' option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the '-o fsc' option. As a result, NFS no longer enables caching if the '-o fsc' option is not used. (BZ# 1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the\n__copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n(BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1397739)\n\n* When the 'punching hole' feature of the fallocate utility was used on an ext4 file system inode with extent depth of 1, the extent tree of the inode sometimes became corrupted. With this update, the underlying source code has been fixed, and extent tree corruption no longer occurs in the described situation.

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, Moderate)\n\nBug Fix(es) :\n\n - The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver.\n\n - Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the '-o fsc' option was not used in the mount command.\n Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user.\n With this update, NFS does not use the FS cache if not instructed by the '-o fsc' option. As a result, NFS no longer enables caching if the '-o fsc' option is not used.\n\n - Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs.\n\n - Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs.\n\n - Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the\n __copy_tofrom_user() function was returning incorrect values. This update fixes the __copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario.\n\n - Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances.\n\n - When the 'punching hole' feature of the fallocate utility was used on an ext4 file system inode with extent depth of 1, the extent tree of the inode sometimes became corrupted.

(CVE-2016-2053)\n\n - The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not\n initialize a certain data structure, which allows local users to obtain sensitive information from kernel\n stack memory via crafted use of the ALSA timer interface. (CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which\n allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA\n timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel\n through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by\n changing a certain size value, aka a double fetch vulnerability. (CVE-2016-6480)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel\n before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service\n (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a\n certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted\n with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute\n untrusted code by appending ACPI tables to the initrd. (CVE-2016-3699)\n\n - Use-after-free vulnerability in mm/percpu.c in the Linux kernel through 4.6 allows local users to cause a\n denial of service (BUG) or possibly have unspecified other impact via crafted use of the mmap and bpf\n system calls. (CVE-2016-4794)\n\n - Race condition in the audit_log_single_execve_arg function in kernel/auditsc.c in the Linux kernel through\n 4.7 allows local users to bypass intended character-set restrictions or disrupt system-call auditing by\n changing a certain string, aka a double fetch vulnerability.

An attacker on a local network could potentially send a sequence of specially crafted packets that would initiate the loading of a large number of extensions, causing the targeted system in that network to crash.(CVE-2014-9715i1/4%0\n\n - A flaw was found in the Linux kernel which could cause a kernel panic when restoring machine specific registers on the PowerPC platform. Incorrect transactional memory state registers could inadvertently change the call path on return from userspace and cause the kernel to enter an unknown state and crash.(CVE-2015-8844i1/4%0\n\n - A timing flaw was found in the Chrome EC driver in the Linux kernel. An attacker could abuse timing to skip validation checks to copy additional data from userspace possibly increasing privilege or crashing the system.(CVE-2016-6156i1/4%0\n\n - A race condition flaw was found in the way the Linux kernel's IPC subsystem initialized certain fields in an IPC object structure that were later used for permission checking before inserting the object into a globally visible list. A local, unprivileged user could potentially use this flaw to elevate their privileges on the system.(CVE-2015-7613i1/4%0\n\n - A path length checking flaw was found in Linux kernels built with UDF file system (CONFIG_UDF_FS) support. An attacker able to mount a corrupted/malicious UDF file system image could use this flaw to leak kernel memory to user-space.(CVE-2014-9731i1/4%0\n\n - 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-2017-2671i1/4%0\n\n - The f2fs implementation in the Linux kernel, before 4.14, mishandles reference counts associated with f2fs_wait_discard_bios calls. This allows local users to cause a denial of service (BUG), as demonstrated by fstrim.(CVE-2017-18200i1/4%0\n\n - The LIST_POISON feature in include/linux/poison.h in the Linux kernel before 4.3, as used in Android 6.0.1 before 2016-03-01, does not properly consider the relationship to the mmap_min_addr value, which makes it easier for attackers to bypass a poison-pointer protection mechanism by triggering the use of an uninitialized list entry, aka Android internal bug 26186802, a different vulnerability than CVE-2015-3636.(CVE-2016-0821i1/4%0\n\n - The xsave/xrstor implementation in arch/x86/include/asm/xsave.h in the Linux kernel before 3.19.2 creates certain .altinstr_replacement pointers and consequently does not provide any protection against instruction faulting, which allows local users to cause a denial of service (panic) by triggering a fault, as demonstrated by an unaligned memory operand or a non-canonical address memory operand.(CVE-2015-2672i1/4%0\n\n - The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the 'LECHO i1/4+ !OPOST' case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.(CVE-2014-0196i1/4%0\n\n - 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-2018-5344i1/4%0\n\n - The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-length write operation.(CVE-2013-6378i1/4%0\n\n - A NULL-pointer dereference vulnerability was discovered in the Linux kernel. The kernel's Reliable Datagram Sockets (RDS) protocol implementation did not verify that an underlying transport existed before creating a connection to a remote server. A local system user could exploit this flaw to crash the system by creating sockets at specific times to trigger a NULL pointer dereference.(CVE-2015-6937i1/4%0\n\n - A stack buffer overflow flaw was found in the way the Bluetooth subsystem of the Linux kernel processed pending L2CAP configuration responses from a client. On systems with the stack protection feature enabled in the kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other than s390x and ppc64le), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to crash the system. Due to the nature of the stack protection feature, code execution cannot be fully ruled out, although we believe it is unlikely. On systems without the stack protection feature (ppc64le the Bluetooth modules are not built on s390x), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to remotely execute arbitrary code on the system with ring 0 (kernel) privileges.(CVE-2017-1000251i1/4%0\n\n - Integer signedness error in the MSM QDSP6 audio driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to gain privileges or cause a denial of service (memory corruption) via a crafted application that makes an ioctl call.(CVE-2016-2066i1/4%0\n\n - The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in the Linux kernel before 3.12 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call.(CVE-2013-4515i1/4%0\n\n - A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled malformed Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system.(CVE-2014-3673i1/4%0\n\n - It was found that paravirt_patch_call/jump() functions in the arch/x86/kernel/paravirt.c in the Linux kernel mishandles certain indirect calls, which makes it easier for attackers to conduct Spectre-v2 attacks against paravirtualized guests.(CVE-2018-15594i1/4%0\n\n - It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system.(CVE-2014-3690i1/4%0\n\n - A flaw was found in the Linux kernel's ext4 filesystem.\n A local user can cause an out-of-bound write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.(CVE-2018-10883i1/4%0\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

This allows local users to obtain sensitive information from uninitialized kernel memory via crafted use of the mincore() system call.(CVE-2017-16994)In the Linux kernel before 4.7, the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free.(CVE-2017-18174)In the Linux kernel through 4.20.11, af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr.(CVE-2019-8912)A security flaw was found in the Linux kernel that an attempt to move page mapped by AIO ring buffer to the other node triggers NULL pointer dereference at trace_writeback_dirty_page(), because aio_fs_backing_dev_info.dev is 0.(CVE-2016-3070)The NFSv4 implementation in the Linux kernel through 4.11.1 allows local users to cause a denial of service (resource consumption) by leveraging improper channel callback shutdown when unmounting an NFSv4 filesystem, aka a 'module reference and kernel daemon' leak.(CVE-2017-9059)When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.(CVE-2016-6136)A use-after-free vulnerability was found in a network namespaces code affecting the Linux kernel since v4.0-rc1 through v4.15-rc5. The function get_net_ns_by_id() does not check for the net::count value after it has found a peer network in netns_ids idr which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.(CVE-2017-15129)A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS).

This flaw panics the machine during the verification of the RSA key.(CVE-2016-8650)The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511.(CVE-2013-6763)In the Linux kernel before 4.20.5, attackers can trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a 'service ipmievd restart' loop.(CVE-2019-9003)An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four.(CVE-2015-1593)The compat_sys_recvmmsg function in net/compat.c in the Linux kernel before 3.13.2, when CONFIG_X86_X32 is enabled, allows local users to gain privileges via a recvmmsg system call with a crafted timeout pointer parameter.(CVE-2014-0038)The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.(CVE-2018-10124)arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction.(CVE-2014-2039)A flaw was found in the Linux kernel in that the aoedisk_debugfs_show() function in drivers/block/aoe/aoeblk.c allows local users to obtain some kernel address information by reading a debugfs file. This address is not useful to commit a further attack.(CVE-2018-7754)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. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access.(CVE-2018-7566)In the function wmi_set_ie(), the length validation code does not handle unsigned integer overflow properly. As a result, a large value of the 'ie_len' argument can cause a buffer overflow in all Android releases from CAF (Android for MSM, Firefox OS for MSM, QRD Android) using the Linux Kernel.(CVE-2018-5848)The Linux kernel does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.(CVE-2018-1118)Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.(CVE-2018-3639)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

There is an information leak in file 'sound/core/timer.c' of the latest mainline Linux kernel, the stack object aEURoetreadaEUR has a total size of 32 bytes. It contains a 8-bytes padding, which is not initialized but sent to user via copy_to_user(), resulting a kernel leak.(CVE-2016-4569)\n\n - A vulnerability was found in Linux kernel. There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object aEURoer1aEUR has a total size of 32 bytes. Its field aEURoeeventaEUR and aEURoevalaEUR both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.(CVE-2016-4578)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.(CVE-2016-4581)\n\n - Use after free vulnerability was found in percpu using previously allocated memory in bpf. First\n __alloc_percpu_gfp() is called, then the memory is freed with free_percpu() which triggers async pcpu_balance_work and then pcpu_extend_area_map could use a chunk after it has been freed.(CVE-2016-4794)\n\n - Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions.(CVE-2016-4805)\n\n - A vulnerability was found in the Linux kernel. Payloads of NM entries are not supposed to contain NUL. When such entry is processed, only the part prior to the first NUL goes into the concatenation (i.e. the directory entry name being encoded by a bunch of NM entries). The process stops when the amount collected so far + the claimed amount in the current NM entry exceed 254. However, the value returned as the total length is the sum of *claimed* sizes, not the actual amount collected. And that's what will be passed to readdir() callback as the name length - 8Kb\n __copy_to_user() from a buffer allocated by\n __get_free_page().(CVE-2016-4913)\n\n - A flaw was discovered in processing setsockopt for 32 bit processes on 64 bit systems. This flaw will allow attackers to alter arbitrary kernel memory when unloading a kernel module. This action is usually restricted to root-privileged users but can also be leveraged if the kernel is compiled with CONFIG_USER_NS and CONFIG_NET_NS and the user is granted elevated privileges.(CVE-2016-4997)\n\n - An out-of-bounds heap memory access leading to a Denial of Service, heap disclosure, or further impact was found in setsockopt(). The function call is normally restricted to root, however some processes with cap_sys_admin may also be able to trigger this flaw in privileged container environments.(CVE-2016-4998)\n\n - A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.(CVE-2016-5195)\n\n - It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696)\n\n - A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system.(CVE-2016-5829)\n\n - When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.(CVE-2016-6136)\n\n - It was found that the unlink and rename functionality in overlayfs did not verify the upper dentry for staleness. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to panic or crash the system.(CVE-2016-6197)\n\n - A flaw was found that the vfs_rename() function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system.(CVE-2016-6198)\n\n - 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-2016-6327)\n\n - A race condition flaw was found in the ioctl_send_fib() function in the Linux kernel's aacraid implementation.\n A local attacker could use this flaw to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value.(CVE-2016-6480)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 30955111.(CVE-2016-6786)\n\n - kernel/events/core.c in the performance subsystem in the Linux kernel before 4.0 mismanages locks during certain migrations, which allows local users to gain privileges via a crafted application, aka Android internal bug 31095224.(CVE-2016-6787)\n\n - A use-after-free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions.\n This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection.(CVE-2016-6828)\n\n - Linux kernel built with the 802.1Q/802.1ad VLAN(CONFIG_VLAN_8021Q) OR Virtual eXtensible Local Area Network(CONFIG_VXLAN) with Transparent Ethernet Bridging(TEB) GRO support, is vulnerable to a stack overflow issue. It could occur while receiving large packets via GRO path, as an unlimited recursion could unfold in both VLAN and TEB modules, leading to a stack corruption in the kernel.(CVE-2016-7039)\n\n - It was found that when the gcc stack protector was enabled, reading the /proc/keys file could cause a panic in the Linux kernel due to stack corruption. This happened because an incorrect buffer size was used to hold a 64-bit timeout value rendered as weeks.(CVE-2016-7042)\n\n - It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAP_FSETID, the setgid bit would be cleared. 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 could allow a local user to gain group privileges via certain setgid applications.(CVE-2016-7097)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

(CVE-2016-3841, Important)\n\n* Several Moderate and Low impact security issues were found in the\nLinux kernel. Space precludes documenting each of these issues in this\nadvisory. Refer to the CVE links in the References section for a\ndescription of each of these vulnerabilities.

(CVE-2016-6136, Moderate)\n\n * A flaw was found in the Linux kernel's implementation of the SCTP\nprotocol. A remote attacker could trigger an out-of-bounds read with an\noffset of up to 64kB potentially causing the system to crash.\n(CVE-2016-9555, Moderate)\n\nBug Fix(es):\n\n * The qlnic driver previously attempted to fetch pending transmission\ndescriptors before all writes were complete, which lead to firmware hangs.\nWith this update, the qlcnic driver has been fixed to complete all writes\nbefore the hardware fetches any pending transmission descriptors. As a\nresult, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n * Previously, when a NFS share was mounted, the file-system (FS) cache was\nincorrectly enabled even when the '-o fsc' option was not used in the mount\ncommand. Consequently, the cachefilesd service stored files in the NFS\nshare even when not instructed to by the user. With this update, NFS does\nnot use the FS cache if not instructed by the '-o fsc' option. As a result,\nNFS no longer enables caching if the '-o fsc' option is not used.\n(BZ#1399172)\n\n * Previously, an NFS client and NFS server got into a NFS4 protocol loop\ninvolving a WRITE action and a NFS4ERR_EXPIRED response when the\ncurrent_fileid counter got to the wraparound point by overflowing the value\nof 32 bits. This update fixes the NFS server to handle the current_fileid\nwraparound. As a result, the described NFS4 protocol loop no longer occurs.\n(BZ#1399174)\n\n * Previously, certain configurations of the Hewlett Packard Smart Array\n(HPSA) devices caused hardware to be set offline incorrectly when the HPSA\ndriver was expected to wait for existing I/O operations to complete.\nConsequently, a kernel panic occurred. This update prevents the described\nproblem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n * Previously, memory corruption by copying data into the wrong memory\nlocations sometimes occurred, because the __copy_tofrom_user() function was\nreturning incorrect values.

As a\nresult, the firmware no longer hangs with the qlcnic driver.

Marvel of the United States Army Research Laboratory discovered\nthat Linux's implementation of the TCP Challenge ACK feature\nresults in a side channel that can be used to find TCP connections\nbetween specific IP addresses, and to inject messages into those\nconnections.\n\nWhere a service is made available through TCP, this may allow\nremote attackers to impersonate another connected user to the\nserver or to impersonate the server to another connected user. In\ncase the service uses a protocol with message authentication\n(e.g. TLS or SSH), this vulnerability only allows denial of\nservice (connection failure). An attack takes tens of seconds, so\nshort-lived TCP connections are also unlikely to be vulnerable.\n\nThis may be mitigated by increasing the rate limit for TCP\nChallenge ACKs so that it is never exceeded:\nsysctl net.ipv4.tcp_challenge_ack_limit=1000000000\n\nCVE-2016-6136Pengfei Wang discovered that the audit subsystem has a\n'double-fetch' or TOCTTOU \nbug in its handling of special\ncharacters in the name of an executable. Where audit logging of\nexecve() is enabled, this allows a local user to generate\nmisleading log messages.\n\nCVE-2016-6480Pengfei Wang discovered that the aacraid driver for Adaptec RAID\ncontrollers has a 'double-fetch' or TOCTTOU bug in its\nvalidation of FIB \nmessages passed through the ioctl() system\ncall. This has no practical security impact in current Debian\nreleases.\n\nCVE-2016-6828 \nMarco Grassi reported a 'use-after-free' bug in the TCP\nimplementation, which can be triggered by local users.

There is an information leak in file sound/core/timer.c of the latest mainline Linux kernel. The stack object r1 has a total size of 32 bytes. Its field event and val both contain 4 bytes padding. These 8 bytes padding bytes are sent to user without being initialized.(CVE-2016-4578)\n\nThe x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)\n\nfs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls.(CVE-2016-4581)\n\nUse after free vulnerability was found in percpu using previously allocated memory in bpf.

(CVE-2016-6136, Moderate)\n\n* 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, Moderate)\n\nBug Fix(es):\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the \"-o fsc\" option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the \"-o fsc\" option. As a result, NFS no longer enables caching if the \"-o fsc\" option is not used. (BZ#1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the __copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario. (BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances.

(CVE-2016-6136, Moderate)\n\n* 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, Moderate)\n\nBug Fix(es):\n\n* The qlnic driver previously attempted to fetch pending transmission descriptors before all writes were complete, which lead to firmware hangs. With this update, the qlcnic driver has been fixed to complete all writes before the hardware fetches any pending transmission descriptors. As a result, the firmware no longer hangs with the qlcnic driver. (BZ#1403143)\n\n* Previously, when a NFS share was mounted, the file-system (FS) cache was incorrectly enabled even when the \"-o fsc\" option was not used in the mount command. Consequently, the cachefilesd service stored files in the NFS share even when not instructed to by the user. With this update, NFS does not use the FS cache if not instructed by the \"-o fsc\" option. As a result, NFS no longer enables caching if the \"-o fsc\" option is not used. (BZ#1399172)\n\n* Previously, an NFS client and NFS server got into a NFS4 protocol loop involving a WRITE action and a NFS4ERR_EXPIRED response when the current_fileid counter got to the wraparound point by overflowing the value of 32 bits. This update fixes the NFS server to handle the current_fileid wraparound. As a result, the described NFS4 protocol loop no longer occurs. (BZ#1399174)\n\n* Previously, certain configurations of the Hewlett Packard Smart Array (HPSA) devices caused hardware to be set offline incorrectly when the HPSA driver was expected to wait for existing I/O operations to complete. Consequently, a kernel panic occurred. This update prevents the described problem. As a result, the kernel panic no longer occurs. (BZ#1399175)\n\n* Previously, memory corruption by copying data into the wrong memory locations sometimes occurred, because the __copy_tofrom_user() function was returning incorrect values. This update fixes the __copy_tofrom_user() function so that it no longer returns larger values than the number of bytes it was asked to copy. As a result, memory corruption no longer occurs in he described scenario. (BZ#1398185)\n\n* Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1397739)\n\n* When the \"punching hole\" feature of the fallocate utility was used on an ext4 file system inode with extent depth of 1, the extent tree of the inode sometimes became corrupted. With this update, the underlying source code has been fixed, and extent tree corruption no longer occurs in the described situation.
