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.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0769 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2026-54059:
    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-2026-54060:
    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-2026-55379:
    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-2026-55380:
    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.
