[SECURITY] [DLA 1862-1] linux security update

Package        : linux
Version        : 3.16.70-1
CVE ID         : CVE-2019-2101 CVE-2019-10639 CVE-2019-13272
Debian Bug     : 930904

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


    Andrey Konovalov discovered that the USB Video Class driver
    (uvcvideo) did not consistently handle a type field in device
    descriptors, which could result in a heap buffer overflow.  This
    could be used for denial of service or possibly for privilege


    Amit Klein and Benny Pinkas discovered that the generation of IP
    packet IDs used a weak hash function that incorporated a kernel
    virtual address.  In Linux 3.16 this hash function is not used for
    IP IDs but is used for other purposes in the network stack.  In
    custom kernel configurations that enable kASLR, this might weaken


    Jann Horn discovered that the ptrace subsystem in the Linux kernel
    mishandles the management of the credentials of a process that wants
    to create a ptrace relationship, allowing a local user to obtain root
    privileges under certain scenarios.

For Debian 8 "Jessie", these problems have been fixed in version
3.16.70-1.  This update also fixes a regression introduced by the
original fix for CVE-2019-11478 (#930904), and includes other fixes
from upstream stable updates.

We recommend that you upgrade your linux and linux-latest
packages.  You will need to use "apt-get upgrade --with-new-pkgs"
or "apt upgrade" as the binary package names have changed.

We recommend that you upgrade your linux packages.
