This update addresses the issue. We apologize for the inconvenience.

Original advisory details:

 It was discovered that the stack guard page for processes in the Linux
 kernel was not sufficiently large enough to prevent overlapping with the
 heap. An attacker could leverage this with another vulnerability to execute
 arbitrary code and gain administrative privileges (CVE-2017-1000364)

 Jesse Hertz and Tim Newsham discovered that the Linux netfilter
 implementation did not correctly perform validation when handling 32 bit
 compatibility IPT_SO_SET_REPLACE events on 64 bit platforms. A local
 unprivileged attacker could use this to cause a denial of service (system
 crash) or execute arbitrary code with administrative privileges.
 (CVE-2016-4997)");
