It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-2013 advisory.

    Pillow is a Python imaging library. Prior to 12.3.0, when Pillow loads an uncompressed McIdas AREA image     from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride     smaller than the natural row width, causing pixel access such as Image.tobytes(), getpixel, convert, or     save to read beyond the mapped region and disclose adjacent process memory or fault. This issue is fixed     in version 12.3.0. (CVE-2026-54058)

    Pillow is a Python imaging library. Prior to 12.3.0, Pillow's public rank-filter API can trigger a native     heap out-of-bounds write when given a very large odd filter size because ImageFilter.RankFilter.filter()     calls image.expand(size // 2, size // 2) before rank-filter size validation and ImagingExpand() computes     output dimensions with unchecked signed int arithmetic. This issue is fixed in version 12.3.0.
    (CVE-2026-59197)

    Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its     packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap     bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0. (CVE-2026-59198)

    Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a     native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in     Image.paste(), Image.crop(), or Image.alpha_composite(). This issue is fixed in version 12.3.0.
    (CVE-2026-59199)

    Pillow is a Python imaging library. From 5.1.0 until 12.3.0, PdfParser.PdfStream.decode() in     PIL/PdfParser.py calls zlib.decompress() with bufsize set to the PDF stream Length field without bounding     the decompressed output size, allowing a crafted FlateDecode PDF stream to exhaust memory from a small     file. This issue is fixed in version 12.3.0. (CVE-2026-59200)

    Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates     total_component_width across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a     crafted tiled JPEG2000 file to force substantially higher transient memory usage and trigger out-of-memory     failures during decoding. This issue is fixed in version 12.3.0. (CVE-2026-59204)

    Pillow is a Python imaging library. Prior to 12.3.0, Pillow's ImageCms.ImageCmsTransform.apply(im, imOut)     API can trigger controlled native heap corruption when the caller supplies an output image whose mode does     not match the transform's declared output mode. This issue is fixed in version 12.3.0. (CVE-2026-59205)
