CVE-2016-1773
The code-signing subsystem in Apple OS X before 10.11.4 does not properly verify file ownership, which allows local users to determine the existence of arbitrary files via unspecified vectors.
Does this matter?
Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.
