    CVE-2009-2347

    Multiple integer overflows in inter-color spaces conversion tools in libtiff 3.8 through 3.8.2, 3.9, and 4.0 allow context-dependent attackers to execute arbitrary code via a TIFF image with large (1) width and (2) height values, which triggers a heap-based buffer overflow in the (a) cvt_whole_image function in tiff2rgba and (b) tiffcvt function in rgb2ycbcr.
