  - A type confusion error exists related to 'IOSurface' and
    serialized object handling that allow arbitrary code
    execution. (CVE-2015-1061)

  - An error exists in 'MobileStorageMounter' related to
    developer disk mounting logic and invalid disk image
    folders that allows a malicious application to create
    folders in trusted locations. (CVE-2015-1062)

  - A security feature bypass vulnerability, known as FREAK
    (Factoring attack on RSA-EXPORT Keys), exists due to the
    support of weak EXPORT_RSA cipher suites with keys less
    than or equal to 512 bits. A man-in-the-middle attacker
    may be able to downgrade the SSL/TLS connection to use
    EXPORT_RSA cipher suites which can be factored in a
    short amount of time, allowing the attacker to intercept
    and decrypt the traffic. (CVE-2015-1067)");
