Name of the Vulnerable Software and Affected Versions
Pillow versions 5.1.0 through 12.2.x
Description
The
PdfParser.PdfStream.decode() function in PIL/PdfParser.py calls zlib.decompress() using the PDF stream Length field for the bufsize parameter without limiting the size of the decompressed output. This allows a specially crafted FlateDecode PDF stream to cause memory exhaustion, even when processing a small file.Recommendations
Update to version 12.3.0.
