CVE-2019-12616
Debian Bug : 930017
Multiple security vulnerabilities were fixed in phpmyadmin, a MySQL web
administration tool, which prevent possible SQL injection attacks, CSRF,
the bypass of user restrictions, information disclosure or
denial-of-service.
For Debian 8 "Jessie", these problems have been fixed in version
4:4.2.12-2+deb8u6.
We recommend that you upgrade your phpmyadmin packages.

DLA 1823-1: linux security update
Package : linux
Version : 3.16.68-2
CVE ID : CVE-2019-3846 CVE-2019-5489 CVE-2019-10126 CVE-2019-11477
CVE-2019-11478 CVE-2019-11479 CVE-2019-11810 CVE-2019-11833
CVE-2019-11884
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.
CVE-2019-3846, CVE-2019-10126
huangwen reported multiple buffer overflows in the Marvell wifi
(mwifiex) driver, which a local user could use to cause denial of
service or the execution of arbitrary code.
CVE-2019-5489
Daniel Gruss, Erik Kraft, Trishita Tiwari, Michael Schwarz, Ari
Trachtenberg, Jason Hennessey, Alex Ionescu, and Anders Fogh
discovered that local users could use the mincore() system call to
obtain sensitive information from other processes that access the
same memory-mapped file.
CVE-2019-11477
Jonathan Looney reported that a specially crafted sequence of TCP
selective acknowledgements (SACKs) allows a remotely triggerable
kernel panic.
CVE-2019-11478
Jonathan Looney reported that a specially crafted sequence of TCP
selective acknowledgements (SACKs) will fragment the TCP
retransmission queue, allowing an attacker to cause excessive
resource usage.
CVE-2019-11479
Jonathan Looney reported that an attacker could force the Linux
kernel to segment its responses into multiple TCP segments, each of
which contains only 8 bytes of data, drastically increasing the
bandwidth required to deliver the same amount of data.
This update introduces a new sysctl value to control the minimal MSS
(net.ipv4.tcp_min_snd_mss), which by default uses the formerly hard-
coded value of 48. We recommend raising this to 512 unless you know
that your network requires a lower value. (This value applies to
Linux 3.16 only.)
CVE-2019-11810
It was discovered that the megaraid_sas driver did not correctly
handle a failed memory allocation during initialisation, which
could lead to a double-free. This might have some security
impact, but it cannot be triggered by an unprivileged user.
CVE-2019-11833
It was discovered that the ext4 filesystem implementation writes
uninitialised data from kernel memory to new extent blocks. A
local user able to write to an ext4 filesystem and then read the
filesystem image, for example using a removable drive, might be
able to use this to obtain sensitive information.
CVE-2019-11884
It was discovered that the Bluetooth HIDP implementation did not
ensure that new connection names were null-terminated. A local
user with CAP_NET_ADMIN capability might be able to use this to
obtain sensitive information from the kernel stack.
For Debian 8 "Jessie", these problems have been fixed in version
3.16.68-2. Packages for PC architectures (amd64 and i386) are already
available, and packages for Arm architectures (armel and armhf) will be
available soon.
We recommend that you upgrade your linux packages.

CVE-2019-9500, CVE-2019-9503
Hugues Anguelkov discovered a buffer overflow and missing access
validation in the Broadcom FullMAC wifi driver (brcmfmac), which a
attacker on the same wifi network could use to cause denial of
service or the execution of arbitrary code.
CVE-2019-11477
Jonathan Looney reported that a specially crafted sequence of TCP
selective acknowledgements (SACKs) allows a remotely triggerable
kernel panic.

CVE-2019-11486
Jann Horn of Google reported numerous race conditions in the
Siemens R3964 line discipline. A local user could use these to
cause unspecified security impact. This module has therefore been
disabled.
CVE-2019-11599
Jann Horn of Google reported a race condition in the core dump
implementation which could lead to a use-after-free. A local
user could use this to read sensitive information, to cause a
denial of service (memory corruption), or for privilege
escalation.
CVE-2019-11815
It was discovered that a use-after-free in the Reliable Datagram
Sockets protocol could result in denial of service and potentially
privilege escalation. This protocol module (rds) is not auto-
loaded on Debian systems, so this issue only affects systems where
it is explicitly loaded.
CVE-2019-11833
It was discovered that the ext4 filesystem implementation writes
uninitialised data from kernel memory to new extent blocks. A
local user able to write to an ext4 filesystem and then read the
filesystem image, for example using a removable drive, might be
able to use this to obtain sensitive information.
CVE-2019-11884
It was discovered that the Bluetooth HIDP implementation did not
ensure that new connection names were null-terminated. A local
user with CAP_NET_ADMIN capability might be able to use this to
obtain sensitive information from the kernel stack.
For the stable distribution (stretch), these problems have been fixed in
version 4.9.168-1+deb9u3.
We recommend that you upgrade your linux packages.
