We recommend that all users of Ksplice Uptrack running RHCK 7 install
these updates.

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

DESCRIPTION

* CVE-2018-14646: Denial-of-service in network namespace netlink capabilities.

A NULL pointer dereference in the netlink code for a network namespaced
process could result in a kernel crash.  A local user in the namespace
could use this flaw to crash the host.


* CVE-2018-14633: Remote privilege escalation in iSCSI CHAP authentication.

A stack buffer overflow in the iSCSI CHAP authentication code could
allow an unauthenticated remote attacker to corrupt stack memory and
crash the system or potentially, execute code on the target system.
