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...

Pillow `BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading
Summary PIL/BdfFontFile.py bdfchar lines 84–88 reads the BBX width height field from a BDF font file and passes the dimensions directly to Image.new without calling Image.decompressionbombcheck. This completely bypasses Pillow's documented decompression bomb protection. Image.open enforces...

GHSA-5X94-69RX-G8H2 Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`
Description PIL/FontFile.py FontFile.compile assembles per-glyph images into a single combined bitmap using Image.new"1", xsize, ysize without calling Image.decompressionbombcheck. This is the base-class method shared by both BdfFontFile and PcfFontFile, and it is triggered whenever a loaded font...

Pillow `PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading
Description PIL/PcfFontFile.py loadbitmaps line 227 reads glyph dimensions from the PCF METRICS section and passes them directly to Image.frombytes without calling Image.decompressionbombcheck. Dimensions originate from unsigned 16-bit values: xsize = right - left max: 65535 − 0 = 65535 ysize =...

urllib3: urllib3: Denial of Service due to excessive HTTP response decompression
A flaw was found in urllib3, an HTTP client library for Python. This vulnerability allows a remote attacker to cause excessive resource consumption, such as high CPU usage and massive memory allocation, on the client side. This occurs when urllib3 attempts to decompress an entire HTTP response,...
