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

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

Bj&oslash;rn 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.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - In the ea_get function in fs/jfs/xattr.c in the Linux     kernel through 4.17.1, a memory corruption bug in JFS     can be triggered by calling setxattr twice with two     different extended attribute names on the same file.
    This vulnerability can be triggered by an unprivileged     user with the ability to create files and execute     programs. A kmalloc call is incorrect, leading to     slab-out-of-bounds in jfs_xattr.(CVE-2018-12233i1/4%0

  - The spectre_v2_select_mitigation function in     arch/x86/kernel/cpu/bugs.c in the Linux kernel before     4.18.1 does not always fill RSB upon a context switch,     which makes it easier for attackers to conduct     userspace-userspace spectreRSB     attacks.(CVE-2018-15572i1/4%0

  - Race condition in the queue_delete function in     sound/core/seq/seq_queue.c in the Linux kernel before     4.4.1 allows local users to cause a denial of service     (use-after-free and system crash) by making an ioctl     call at a certain time.(CVE-2016-2544i1/4%0

  - A flaw was found in the Linux kernel's implementation     of BPF in which systems can application can overflow a     32 bit refcount in both program and map refcount. This     refcount can wrap and end up a user after     free.(CVE-2016-4558i1/4%0

  - Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block     device.(CVE-2013-4299i1/4%0

  - The imon_probe function in drivers/media/rc/imon.c in     the Linux kernel through 4.13.11 allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16537i1/4%0

  - A vulnerability in the handling of Transactional Memory     on powerpc systems was found. An unprivileged local     user can crash the kernel by starting a transaction,     suspending it, and then calling any of the exec() class     system calls.(CVE-2016-5828i1/4%0

  - A cross-boundary flaw was discovered in the Linux     kernel software raid driver. The driver accessed a     disabled bitmap where only the first byte of the buffer     was initialized to zero. This meant that the rest of     the request (up to 4095 bytes) was left and copied into     user space. An attacker could use this flaw to read     private information from user space that would not     otherwise have been accessible.(CVE-2015-5697i1/4%0

  - The parse_hid_report_descriptor function in     drivers/input/tablet/gtco.c in the Linux kernel before     4.13.11 allows local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB     device.(CVE-2017-16643i1/4%0

  - Race condition in the sclp_ctl_ioctl_sccb function in     drivers/s390/char/sclp_ctl.c in the Linux kernel before     4.6 allows local users to obtain sensitive information     from kernel memory by changing a certain length value,     aka a 'double fetch' vulnerability.(CVE-2016-6130i1/4%0

  - drivers/net/usb/asix_devices.c in the Linux kernel     through 4.13.11 allows local users to cause a denial of     service (NULL pointer dereference and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16647i1/4%0

  - 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-2015-8845i1/4%0

  - fs/namespace.c in the Linux kernel through 3.16.1 does     not properly restrict clearing MNT_NODEV, MNT_NOSUID,     and MNT_NOEXEC and changing MNT_ATIME_MASK during a     remount of a bind mount, which allows local users to     gain privileges, interfere with backups and auditing on     systems that had atime enabled, or cause a denial of     service (excessive filesystem updating) on systems that     had atime disabled via a 'mount -o remount' command     within a user namespace.(CVE-2014-5207i1/4%0

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in     denial of service.(CVE-2017-7645i1/4%0

  - The time subsystem in the Linux kernel, when     CONFIG_TIMER_STATS is enabled, allows local users to     discover real PID values (as distinguished from PID     values inside a PID namespace) by reading the     /proc/timer_list file, related to the print_timer     function in kernel/time/timer_list.c and the
    __timer_stats_timer_set_start_info function in     kernel/time/timer.c.(CVE-2017-5967i1/4%0

  - A vulnerability was found in the Linux kernel where the     keyctl_set_reqkey_keyring() function leaks the thread     keyring. This allows an unprivileged local user to     exhaust kernel memory and thus cause a     DoS.(CVE-2017-7472i1/4%0

  - A flaw was found that can be triggered in     keyring_search_iterator in keyring.c if type-i1/4zmatch     is NULL. A local user could use this flaw to crash the     system or, potentially, escalate their     privileges.(CVE-2017-2647i1/4%0

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911i1/4%0

  - Stack-based buffer overflow in the SET_WPS_IE IOCTL     implementation in wlan_hdd_hostapd.c in the WLAN (aka     Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used     in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to gain privileges via a crafted     application that uses a long WPS IE     element.(CVE-2015-0570i1/4%0

  - The net_ctl_permissions function in net/sysctl_net.c in     the Linux kernel before 3.11.5 does not properly     determine uid and gid values, which allows local users     to bypass intended /proc/sys/net restrictions via a     crafted application.(CVE-2013-4270i1/4%0

    (CVE-2018-10124)

    Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly validate     meta-data information. An attacker could use this to construct a malicious xfs image that, when mounted,     could cause a denial of service (system crash). (CVE-2018-10323)

    Zhong Jiang discovered that a use-after-free vulnerability existed in the NUMA memory policy     implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2018-10675)

    Wen Xu discovered that a buffer overflow existed in the ext4 filesystem implementation in the Linux     kernel. An attacker could use this to construct a malicious ext4 image that, when mounted, could cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-10877)

    Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly keep meta-     data information consistent in some situations. An attacker could use this to construct a malicious ext4     image that, when mounted, could cause a denial of service (system crash). (CVE-2018-10881)

    Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle     corrupted meta data in some situations. An attacker could use this to specially craft an ext4 filesystem     that caused a denial of service (system crash) when mounted. (CVE-2018-1092)

    Wen Xu discovered that the ext4 filesystem implementation in the Linux kernel did not properly handle     corrupted meta data in some situations. An attacker could use this to specially craft an ext4 filesystem     that caused a denial of service (system crash) when mounted. (CVE-2018-1093)

    It was discovered that the cdrom driver in the Linux kernel contained an incorrect bounds check. A local     attacker could use this to expose sensitive information (kernel memory). (CVE-2018-10940)

    Shankara Pailoor discovered that the JFS filesystem implementation in the Linux kernel contained a buffer     overflow when handling extended attributes. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2018-12233)

    Wen Xu discovered that the XFS filesystem implementation in the Linux kernel did not properly handle an     error condition with a corrupted xfs image. An attacker could use this to construct a malicious xfs image     that, when mounted, could cause a denial of service (system crash). (CVE-2018-13094)

    It was discovered that the Linux kernel did not properly handle setgid file creation when performed by a     non-member of the group. A local attacker could use this to gain elevated privileges. (CVE-2018-13405)

    Silvio Cesare discovered that the generic VESA frame buffer driver in the Linux kernel contained an     integer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly     execute arbitrary code. (CVE-2018-13406)

    Daniel Jiang discovered that a race condition existed in the ipv4 ping socket implementation in the Linux     kernel. A local privileged attacker could use this to cause a denial of service (system crash).
    (CVE-2017-2671)

    It was discovered that an information leak existed in the generic SCSI driver in the Linux kernel. A local     attacker could use this to expose sensitive information (kernel memory). (CVE-2018-1000204)

    It was discovered that a memory leak existed in the Serial Attached SCSI (SAS) implementation in the Linux     kernel. A physically proximate attacker could use this to cause a denial of service (memory exhaustion).
