CVE-2016-1773


TITLE

Apple OS X Vulnerabilities in the presence of arbitrary files in the code signing subsystem

Trust: 0.8

sources: JVNDB: JVNDB-2016-001898

DESCRIPTION

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. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks. Apple Mac OS X 10.11 through 10.11.3 are vulnerable
