Pillow `BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading
Summary PIL/BdfFontFile.py bdfchar lines 84–88 reads the BBX width height field from a BDF font file and passes the dimensions directly to Image.new without calling Image.decompressionbombcheck. This completely bypasses Pillow's documented decompression bomb protection. Image.open enforces...
Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`
Description PIL/FontFile.py FontFile.compile assembles per-glyph images into a single combined bitmap using Image.new"1", xsize, ysize without calling Image.decompressionbombcheck. This is the base-class method shared by both BdfFontFile and PcfFontFile, and it is triggered whenever a loaded font...

Pillow `PcfFontFile._load_bitmaps()`: `Image.frombytes()` called without `_decompression_bomb_check()` — bomb protection bypass via PCF font loading
Description PIL/PcfFontFile.py loadbitmaps line 227 reads glyph dimensions from the PCF METRICS section and passes them directly to Image.frombytes without calling Image.decompressionbombcheck. Dimensions originate from unsigned 16-bit values: xsize = right - left max: 65535 − 0 = 65535 ysize =...

CVE-2026-53402
A flaw was found in the Linux kernel's framebuffer console fbcon component. When the fbcondosetfont function fails, the system's error handling does not correctly restore the font state, leading to a desynchronized terminal. A local user can exploit this by providing character indices that cause ...
USN-8560-1: libXfont vulnerabilities
It was discovered that libXfont incorrectly handled scaling bitmap fonts, leading to a heap buffer overflow. An attacker able to access the X server could use this issue to cause libXfont to crash, resulting in a denial of service, or possibly execute arbitrary code. CVE-2026-56001 It was...
