Debian 8: DLA-1862-1 Moderate: Linux Kernel Privilege Escalation

debian lts
Calendar Grey July 23, 2019
Dist Debian Esm H88
Updating Linux 3.16.70-2 addresses issues with security escalations, denial of service, and information exposure in the kernel. Implement for Debian LTS today.
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks

Summary

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
