Description:
 Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile
 functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode
 is enabled, allow remote attackers to cause a denial of service (crash) or
 execute arbitrary code via a crafted TIFF image, which triggers an
 out-of-bounds write.
