                 CVE-2017-11176 CVE-2017-1000365

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

CVE-2017-7346

    Li Qiang discovered that the DRM driver for VMware virtual GPUs does
    not properly check user-controlled values in the
    vmw_surface_define_ioctl() functions for upper limits. A local user
    can take advantage of this flaw to cause a denial of service.

CVE-2017-7482

    Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does
    not properly verify metadata, leading to information disclosure,
    denial of service or potentially execution of arbitrary code.

CVE-2017-7533

    Fan Wu and Shixiong Zhao discovered a race condition between inotify
    events and VFS rename operations allowing an unprivileged local
    attacker to cause a denial of service or escalate privileges.

CVE-2017-7541

    A buffer overflow flaw in the Broadcom IEEE802.11n PCIe SoftMAC WLAN
    driver could allow a local user to cause kernel memory corruption,
    leading to a denial of service or potentially privilege escalation.

CVE-2017-7542

    An integer overflow vulnerability in the ip6_find_1stfragopt()
    function was found allowing a local attacker with privileges to open
    raw sockets to cause a denial of service.

CVE-2017-9605

    Murray McAllister discovered that the DRM driver for VMware virtual
    GPUs does not properly initialize memory, potentially allowing a
    local attacker to obtain sensitive information from uninitialized
    kernel memory via a crafted ioctl call.

CVE-2017-10810

    Li Qiang discovered a memory leak flaw within the VirtIO GPU driver
    resulting in denial of service (memory consumption).

CVE-2017-10911 / XSA-216

    Anthony Perard of Citrix discovered an information leak flaw in Xen
    blkif response handling, allowing a malicious unprivileged guest to
    obtain sensitive information from the host or other guests.

CVE-2017-11176

    It was discovered that the mq_notify() function does not set the
    sock pointer to NULL upon entry into the retry logic. An attacker
    can take advantage of this flaw during a user-space close of a
    Netlink socket to cause a denial of service or potentially cause
    other impact.

CVE-2017-1000365

    It was discovered that argument and environment pointers are not
    taken properly into account to the imposed size restrictions on
    arguments and environmental strings passed through
    RLIMIT_STACK/RLIMIT_INFINITY. A local attacker can take advantage of
    this flaw in conjunction with other flaws to execute arbitrary code.

For the oldstable distribution (jessie), these problems will be fixed in
a subsequent DSA.

For the stable distribution (stretch), these problems have been fixed in
version 4.9.30-2+deb9u3.

We recommend that you upgrade your linux packages.
