    	An invalid pointer dereference allows execution of arbitrary
    	code using crafted Type 1 fonts.
    
    CVE-2011-1552
    	Another invalid pointer dereference results in an application
    	crash, triggered by crafted Type 1 fonts.
    
    CVE-2011-1553
    	A use-after-free vulnerability results in an application
    	crash, triggered by crafted Type 1 fonts.
