    [+] Summary    :  A logic flaw in the processing of the ProfileHueSatMapDims (0xC6F5) tag within the Adobe DNG SDK can lead to an integer overflow condition when parsing crafted DNG files.
                      By supplying excessively large dimension values (e.g., 0x15555554) in the Hue/Saturation map metadata, 
    				  an attacker can trigger incorrect memory size calculations during allocation or processing. 
    				  
    [+] This may result in:
    
    Application crash (Denial of Service)
    
    Memory corruption
    
    Potential heap-related instability depending on compilation and runtime protections
    
    The vulnerability occurs due to insufficient validation of multiplication operations involving attacker-controlled dimension fields before memory allocation.
    
    A specially crafted DNG file can trigger the flaw when opened or processed by applications relying on vulnerable versions of the SDK developed by Adobe.
