INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on Virtuozzo 4.7 or
OpenVZ on RHEL 6 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
* Remote denial-of-service in Brocade Ethernet driver.
The Brocade Ethernet driver was failing to account erroneous packets
received, causing endless interrupts. A remote attacker use this flaw to
trigger these never ending interrupts.
* Improved fix to CVE-2015-7872: Denial-of-service when garbage collecting uninstantiated keyring.
A logic error in the security keyring subsystem leads to a kernel crash
when garbage collecting a un-instantiated keyring. A local, un-privileged
user can use this flaw to cause a denial-of-service.
* CVE-2015-7613: Privilege escalation in IPC object initialization.
Incorrect initialization of IPC objects could result in memory
corruption when creating message queues or shared memory. A local,
unprivileged user could use this flaw to escalate privileges.
