INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on EL 5 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-2015-1421: Privilege escalation in SCTP INIT collisions.

Missing reference counting could result in a use-after-free during an
INIT collision when establishing an SCTP socket.  A remote attacker
could use this flaw to trigger a denial-of-service or potentially gain
privileges.


* CVE-2015-2150: Denial-of-service in Xen PCI passthrough devices.

Incorrect restrictions to PCI device configuration could allow a
privileged user in a Xen guest to trigger a fatal NMI in the host.  A
privileged, local user could use this flaw to cause a denial-of-service.


* CVE-2014-8159: Privilege escalation in Infiniband userspace access.

Missing sanitization of userspace input to the Infiniband userspace
memory access subsystem could allow a local user with access to the
/dev/infiniband/uverbsX device nodes to crash the system or,
potentially, escalate their privileges on the system.
