MS10-091：OpenType フォント (OTF) ドライバーの脆弱性により、リモートでコードが実行される (2296199)

2011年3月14日
  危険度: : 緊急
  CVE識別番号: CVE-2010-3956,CVE-2010-3957,CVE-2010-3959

  概要

This security update resolves several vulnerabilities in the Windows Open Type Font (OTF) driver, which could allow remote users to execute code remotely on the affected system. When users navigate to a specially crafted OpenType font on a network share via Windows Explorer, the affected control path is triggered and allows the crafted font to take complete control on the system. This could then allow malicious users to remotely install programs; view, change, or delete data; or create new accounts will full user rights.

More specifically, this security update addresses the vulnerabilities by correcting the way by which the OpenType Font (OTF) driver indexes arrays when parsing OpenType fonts, resets pointers when freeing memory, and parses the CMAP table when rendering OpenType fonts.
