INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running UEKR3 3.8.13 on
OL6 and OL7 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
* CVE-2016-8650: NULL pointer dereference in the key management subsystem.
A missing check in the Multiprecision maths library used to implement
RSA digital signature verification could lead to a NULL pointer
dereference. A local user could use this flaw to cause a denial-of-service.
* CVE-2016-9555: Remote denial-of-service due to SCTP state machine memory corruption.
A missing bound-check in one of the state functions caused memory use
beyond what has been allocated. This could lead to memory corruption and
other undefined behaviors.
* Double free in Infiniband ID mapper work cancel.
If an Infiniband ID map work item was canceled while already running,
the cancellation and completion routines could both run, causing the
work item to be freed twice, potentially corrupting memory.
* Denial-of-service when attaching large numbers of Xen paravirt devices.
Incorrect error checking when attaching a large number of Xen paravirt
devices can trigger a BUG_ON and kernel panic when booting or migrating
a virtual machine.
