Vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to lack of bounds checking in [NSBuiltinCharacterSet initWithCoder:] when processing malicious data. A remote attacker can send a specially crafted graphic file, trick the victim into opening it, trigger heap-based buffer overflow in NSUnarchiver and execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in full system compromise.
