CVE-2026-54060

A flaw was found in Pillow, a Python imaging library. When processing a specially crafted font file, the library's font compilation function does not adequately check for excessive memory allocation. This oversight allows a remote attacker to trigger an unreasonable consumption of system memory,...

CVE-2026-55380

A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing a specially crafted GD 2.x image file. The GdImageFile.open function reads image dimensions without proper validation, leading to excessive memory allocation. This can result in a...

CVE-2026-55379

A flaw was found in Pillow, a Python imaging library. This vulnerability allows a remote attacker to cause a Denial of Service DoS by providing a specially crafted BDF font file. The library's image processing function fails to properly validate dimensions from the font file, bypassing a critical...
