INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Virtuozzo 4.7
or OpenVZ on RHEL 6 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2017-17807: Permissions bypass when requesting key on default keyring.

When calling request_key() with no keyring specified, the requested key
is generated and added to the keyring even if the user does not have
write permissions.


* CVE-2017-1000410: Information leak in Bluetooth L2CAP messages.

Incorrect handling of short EFS elements in an L2CAP message could allow
an attacker to leak the contents of kernel memory.


* CVE-2018-1130: Denial-of-service in DCCP message send.

A logic error in the dccp code could lead to a NULL pointer dereference
when transmitting messages, leading to a kernel panic.  An attacker could
use this to cause a denial-of-service.


* CVE-2017-17450: Permission bypass with Passive OS Fingerprinting match module.

A missing permission check when using Passive OS Fingerprinting match
module allows an unprivileged user to modify the global OS fingerprint
list without the proper permissions.


* CVE-2018-6927: Integer overflow when re queuing a futex.

A missing check when calling futex system call with "requeue" option could
lead to an integer overflow. A local attacker could use this flaw to
cause a denial-of-service.


* CVE-2018-8897: Denial-of-service in KVM breakpoint handling.

Incorrect stack management of data watchpoints and breakpoints could
allow an unprivileged user to crash the system.


* CVE-2017-13166: Privilege escalation when using V4L2 ioctls.

Logic errors in multiple V4L2 ioctls could lead to arbitrary execution
of user space defined addresses. A local attacker could use this flaw to escalate
privileges.
