Printing interruption via out-of-bounds slope write
Published Feb 26, 2025 · Updated Feb 26, 2025
Out-of-bounds write in Canon V4 printer drivers 2.1 and earlier allows remote attackers to interrupt printing via crafted XPS files. During curve rendering, slope processing writes beyond its intended memory bounds when parsing attacker-controlled curve data. No authentication or user interaction is required; Canon limits the reported effect to failed printing and reports no data breach.
