"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)
