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

CVE-2019-2101

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 escalation.

CVE-2019-10639

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 kASLR.

CVE-2019-13272

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.
