Pillow: Pillow: Memory disclosure or denial of service via crafted McIdas AREA image

A flaw was found in Pillow prior to 12.3.0. When an uncompressed McIdas AREA image is loaded from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width. Pixel access such as Image.tobytes, getpixel, convert, or save ca...

python-pillow: Pillow: Denial of Service via crafted BDF font file

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...

python-pillow: Pillow: Denial of Service via crafted GD 2.x image file

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...

python-pillow: Pillow: Denial of Service via crafted PCF font data

A flaw was found in Pillow, a Python imaging library. A remote attacker could exploit this vulnerability by providing specially crafted PCF font data. This data, when processed, can lead to excessive memory allocation because the library does not properly check for decompression bombs. The primar...
