TITLE

Apple OS X of Code Signing Vulnerability that can bypass access restrictions

Trust: 0.8

sources: JVNDB: JVNDB-2015-002195

DESCRIPTION

The Code Signing implementation in Apple OS X before 10.10.3 does not properly validate signatures, which allows local users to bypass intended access restrictions via a crafted bundle, a different vulnerability than CVE-2015-1145. Apple Mac OS X is prone to multiple security vulnerabilities that have been addressed in Security Update 2015-004. The update addresses new vulnerabilities that affect the Admin Framework, ATS, CoreAnimation, Graphics Driver, Hypervisor, ImageIO, IOHIDFamily, Kernel, LaunchServices, UniformTypeIdentifiers, Security - Code Signing, Open Directory Client, and Screen Sharing components. Attackers can exploit these issues to execute arbitrary code with system privileges, gain admin privileges, bypass security restrictions, cause denial-of-service conditions, obtain sensitive information and perform other attacks. These issues affect Mac OS X prior to 10.10.3. The vulnerability stems from the fact that the program does not properly verify the signature. The following versions are affected: Apple OS X 10.8.5 and earlier, 10.9.5 and earlier, 10.10.2 and earlier
