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...

SUSE CVE-2026-54060

Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile assembled per-glyph images into a combined bitmap with Image.new"1", xsize, ysize without calling Image.decompressionbombcheck, allowing a font to trigger excessive allocation during conversion or saving. This...

CVE-2026-55380

Pillow is a Python imaging library. Prior to 12.3.0, PIL/GdImageFile.py GdImageFile.open read image dimensions from the GD 2.x header and stored them in self.size without calling Image.decompressionbombcheck, allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This iss...

CVE-2026-54060

The issue affects Pillow (Python imaging library). In FontFile.compile(), per-glyph images were assembled into a single bitmap using Image.new("1", (xsize, ysize)) without calling Image._decompression_bomb_check(), enabling an attacker to trigger excessive memory allocation during conversion or s...

CVE-2026-54059 Pillow: PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading

Pillow is a Python imaging library. Prior to 12.3.0, PIL/PcfFontFile.py loadbitmaps read glyph dimensions from the PCF METRICS section and passed them directly to Image.frombytes without calling Image.decompressionbombcheck, allowing crafted PCF font data to cause excessive memory allocation. Thi...

Buffer over-flow in Pillow

When reading a TGA file with RLE packets that cross scan lines, Pillow reads the information past the end of the first line without deducting that from the length of the remaining file data. This vulnerability was introduced in Pillow 9.1.0, and can cause a heap buffer overflow. Opening an image...
