Description

This security bulletin contains information about 1 security vulnerability.


1) Buffer overflow (CVE-ID: CVE-2017-2522)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to bad bounds checking in NSCharacterSet coding for NSKeyedUnarchiver when processing malicious data. A remote attacker can send a specially crafted NSArchiver object, trick the victim into opening it, trigger buffer overflow in the CoreFoundation component and execute arbitrary code with privileges of the current user.

Successful exploitation of the vulnerability may result in full system compromise.
