Kerentanan Memory Allocation with Excessive Size Value pada python pillow. Skor CVSS 3.1 7.5 (High) menurut github.com.

Deskripsi (NVD)

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._decompression_bomb_check(), allowing a crafted .gd file to trigger excessive C-heap allocation when loaded. This issue is fixed in version 12.3.0.
