In short

A flaw in Windows' font handling allows attackers to crash your computer or run malicious code by sending you a specially crafted font file. This happens because the system doesn't properly check font data boundaries.

Technical detail

Buffer underflow vulnerability in atmfd.dll (Adobe Type Manager Library) allows remote code execution when processing malformed OpenType fonts. The affected Windows versions fail to validate font structure bounds, enabling attackers to write data below allocated buffer memory and execute arbitrary code without user interaction beyond opening the font.
