[Ksplice][Ubuntu-14.04-Updates] New Ksplice updates for Ubuntu 14.04 Trusty (USN-3908-1)

[Oracle Ksplice]

Synopsis: USN-3908-1 can now be patched using Ksplice
CVEs: CVE-2019-6133

Systems running Ubuntu 14.04 Trusty can now use Ksplice to patch
against the latest Ubuntu Security Notice, USN-3908-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Ubuntu 14.04
Trusty 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-2019-6133: Permission bypass of userspace Policykit protection.

When a non-root user try to control a systemd unit, the Policykit asks
for an administrator password. Once entered, polkit caches this password
up to five minutes for corresponding process based on PID and start_time
of the process. A race condition in the fork syscall could let an
attacker spawn a process with same start_time and same PID as targeted
process and thus control a systemd unit.


* NULL pointer dereference when running fstrim on Bcache driver.

A missing check when running fstrim on Bcache driver could lead to a
NULL pointer dereference. A local attacker could use this flaw to cause
a denial-of-service.
