Systems running Debian 8.0 Jessie can now use Ksplice to patch against
the latest Debian kernel update, DLA-1823-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Debian 8.0
Jessie install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2019-3846: Heap overflow when parsing BSS descriptor in Marvell WiFi-Ex driver.

A missing check on user input when parsing BSS descriptor in Marvell
WiFi-Ex driver could let a local attacker cause a heap overflow and a
denial-of-service.


* CVE-2019-10126: Heap overflow when parsing IEs in Marvell WiFi-Ex driver.

A missing check when parsing IEs in Marvell WiFi-Ex driver could lead to
a heap overflow. A local attacker could use this flaw to cause a
denial-of-service.


* CVE-2019-11810: Denial-of-service in LSI Logic MegaRAID probing.

A logic error in the LSI Logic MegaRAID device probing could result in a
NULL pointer dereference and kernel crash under specific conditions.


* CVE-2019-11884: Information leak in Bluetooth HIDP HIDPCONNADD ioctl().

Missing string termination in the Bluetooth HIDP HIDPCONNADD ioctl()
could result in leaking the contents of the kernel stack to a local
user.


* CVE-2019-11833: Information leak in ext4 extent tree block.

A missing zeroing of uninitialized memory in ext4 extent tree block
could lead to an information leak. A local attacker could use this flaw
to leak information about running kernel and facilitate an attack.


* CVE-2019-5489: Information leak in the mincore() syscall implementation.

Missing checks in the mincore() syscall could let a local attacker
observes page cache access patterns on other process in the system and
lead to an information leak.


* CVE-2019-11477, CVE-2019-11478, CVE-2019-11479: Remote Denial-of-service in TCP stack.

A number of errors in the TCP stack could result in a remotely
triggerable denial of service on links with a small Maximum Segment Size
(MSS).  A remote user could use a maliciously crafted TCP stream to
either panic the system or exhaust resources.

A new sysctl, ksplice_net_ipv4.tcp_min_snd_mss can be used to to adjust
the minimum Maximum Segment Size and defaults to 48 bytes.
