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

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-2026-54060

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...

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...
