"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

  - CVE-2017-7487
    Li Qiang reported a reference counter leak in the
    ipxitf_ioctl function which may result into a
    use-after-free vulnerability, triggerable when a IPX
    interface is configured.

  - CVE-2017-7645
    Tuomas Haanpaa and Matti Kamunen from Synopsys Ltd
    discovered that the NFSv2 and NFSv3 server
    implementations are vulnerable to an out-of-bounds
    memory access issue while processing arbitrarily long
    arguments sent by NFSv2/NFSv3 PRC clients, leading to a
    denial of service.

  - CVE-2017-7895
    Ari Kauppi from Synopsys Ltd discovered that the NFSv2
    and NFSv3 server implementations do not properly handle
    payload bounds checking of WRITE requests. A remote
    attacker with write access to a NFS mount can take
    advantage of this flaw to read chunks of arbitrary
    memory from both kernel-space and user-space.

  - CVE-2017-8064
    Arnd Bergmann found that the DVB-USB core misused the
    device logging system, resulting in a use-after-free
    vulnerability, with unknown security impact.

  - CVE-2017-8890
    It was discovered that the net_csk_clone_lock() function
    allows a remote attacker to cause a double free leading
    to a denial of service or potentially have other impact.

  - CVE-2017-8924
    Johan Hovold found that the io_ti USB serial driver
    could leak sensitive information if a malicious USB
    device was connected.

  - CVE-2017-8925
    Johan Hovold found a reference counter leak in the
    omninet USB serial driver, resulting in a use-after-free
    vulnerability. This can be triggered by a local user
    permitted to open tty devices.

  - CVE-2017-9074
    Andrey Konovalov reported that the IPv6 fragmentation
    implementation could read beyond the end of a packet
    buffer. A local user or guest VM might be able to use
    this to leak sensitive information or to cause a denial
    of service (crash).

  - CVE-2017-9075
    Andrey Konovalov reported that the SCTP/IPv6
    implementation wrongly initialised address lists on
    connected sockets, resulting in a use-after-free
    vulnerability, a similar issue to CVE-2017-8890. This
    can be triggered by any local user.

  - CVE-2017-9076 / CVE-2017-9077
    Cong Wang found that the TCP/IPv6 and DCCP/IPv6
    implementations wrongly initialised address lists on
    connected sockets, a similar issue to CVE-2017-9075.

  - CVE-2017-9242
    Andrey Konovalov reported a packet buffer overrun in the
    IPv6 implementation. A local user could use this for
    denial of service (memory corruption; crash) and
    possibly for privilege escalation.

  - CVE-2017-1000364
    The Qualys Research Labs discovered that the size of the
    stack guard page is not sufficiently large. The
    stack-pointer can jump over the guard-page and moving
    from the stack into another memory region without
    accessing the guard-page. In this case no page-fault
    exception is raised and the stack extends into the other
    memory region. An attacker can exploit this flaw for
    privilege escalation.

  The default stack gap protection is set to 256 pages and can be
  configured via the stack_guard_gap kernel parameter on the kernel
  command line.
