and ImageFilter.RankFilter, a JPEG2000 tiled-decode DoS, a decompression
bomb in PdfParser, a TGA RLE encoder heap data leak, an OS command
injection in WindowsViewer.get_command(), several decompression-bomb
check bypasses (GdImageFile, BdfFontFile, FontFile, PcfFontFile), an
out-of-bounds read via row stride on the mmap path, and an infinite
loop DoS in EpsImagePlugin.
