DESCRIPTION

* Improved fix for Spectre v2: Speculative execution when making indirect calls during emulation.

A missing use of indirect calls protection macro during emulation could
lead to speculative execution. A local attacker could use this flaw to
leak information about running system.


* Improved fix for CVE-2017-5715: Denial-of-service when ptracing a process while AppArmor is running.

A logic error when ptracing a process from another process while
AppArmor is enabled could lead to a deadlock. A local
attacker could use this flaw to cause a denial-of-service.
