Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()

Summary PdfParser.PdfStream.decode in Pillow's PdfParser.py calls zlib.decompress with the bufsize parameter set to the value of the PDF stream's Length field, without any upper bound on the actual decompressed output size. Python's zlib.decompress bufsize argument is an initial output buffer hin...

Pillow `GdImageFile._open()`: image dimensions accepted without `_decompression_bomb_check()`

Description PIL/GdImageFile.py GdImageFile.open reads image dimensions from the GD 2.x header and stores them in self.size without calling Image.decompressionbombcheck. Because GdImageFile is not registered with Image.registeropen, it never passes through the standard Image.open code path that...
