TITLE

Apple iOS and Apple OS X of CoreText Vulnerable to arbitrary code execution

DESCRIPTION

CoreText in Apple iOS before 8.4 and OS X before 10.10.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted text file, a different vulnerability than CVE-2015-3685, CVE-2015-3686, CVE-2015-3688, and CVE-2015-3689. Multiple memory-corruption vulnerabilities 2. Multiple information-disclosure vulnerabilities 3. A security vulnerability 4. Multiple buffer-overflow vulnerabilities An attacker can leverage these issues to obtain sensitive information, and execute arbitrary code with system privileges. Failed exploit attempts will likely result in denial-of-service conditions. in the United States. CoreText is one of the text engines that can control text formatting and text layout.
