  script_set_attribute(attribute:"description", value:
"According to the versions of the python-pillow packages installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

    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, 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.(CVE-2026-55380)

    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. Prior to 12.3.0, PIL/BdfFontFile.py bdf_char() read the BBX width and
    height field from a BDF font file and passed attacker-controlled dimensions to Image.new() without calling
    Image._decompression_bomb_check(), bypassing Pillow's documented decompression bomb protection and
    allowing excessive memory allocation. This issue is fixed in version 12.3.0.(CVE-2026-55379)

    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)

    Pillow is a Python imaging library. Prior to 12.3.0, PIL/FontFile.py FontFile.compile() assembled per-
    glyph images into a combined bitmap with Image.new('1', (xsize, ysize)) without calling
    Image._decompression_bomb_check(), allowing a font to trigger excessive allocation during conversion or
    saving. This issue is fixed in version 12.3.0.(CVE-2026-54060)

    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. Prior to 12.3.0, WindowsViewer.get_command() constructed a cmd.exe
    shell command by directly embedding a file path into an f-string without escaping and passed the result to
    subprocess.Popen(..., shell=True), allowing shell metacharacters in the file path to inject arbitrary
    cmd.exe commands. This issue is fixed in version 12.3.0.(CVE-2026-55798)

    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 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. Prior to 12.3.0, PIL/PcfFontFile.py _load_bitmaps() read glyph
    dimensions from the PCF METRICS section and passed them directly to Image.frombytes() without calling
    Image._decompression_bomb_check(), allowing crafted PCF font data to cause excessive memory allocation.
    This issue is fixed in version 12.3.0.(CVE-2026-54059)
