Debian 8: DLA-1919-2 Critical: Linux Kernel Denial of Service Risks

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211)
did not properly authenticate Tunneled Direct Link Setup (TDLS)
messages. A nearby attacker could use this for denial of service
(loss of wifi connectivity).

CVE-2019-9506

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen
discovered a weakness in the Bluetooth pairing protocols, dubbed
the "KNOB attack". An attacker that is nearby during pairing
could use this to weaken the encryption used between the paired
devices, and then to eavesdrop on and/or spoof communication
between them.

This update mitigates the attack by requiring a minimum encryption
key length of 56 bits.

CVE-2019-11487

Jann Horn discovered that the FUSE (Filesystem-in-Userspace)
facility could be used to cause integer overflow in page reference
counts, leading to a use-after-free. On a system with sufficient
physical memory, a local user permitted to create arbitrary FUSE
