In SWFTools 0.9.2, the png_load function in lib/png.c does not properly
validate an alloclen_64 multiplication of width and height values, which
allows remote attackers to cause a denial of service (integer overflow,
heap-based buffer overflow, and application crash) or possibly have
unspecified other impact via a crafted PNG file.
