In short
A flaw in Windows font handling allows attackers to run malicious code by sending a specially crafted TrueType font file. This is dangerous because fonts are often trusted and downloaded automatically by browsers and applications.
Technical detail
The vulnerability exists in win32k.sys kernel-mode driver's TrueType font parsing logic (CWE-94: Improper Control of Generation of Code), allowing remote code execution when a specially crafted font is processed. No user interaction beyond normal font processing is required; the attacker can deliver the malicious font via web browsers or email attachments.
Summary generated and translated by AI from the official description.
win32k.sys in the kernel-mode drivers in Microsoft Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows remote attackers to execute arbitrary code via a crafted TrueType font, as exploited in the wild in October 2014, aka "TrueType Font Parsing Remote Code Execution Vulnerability."
