This security update resolves two privately reported vulnerabilities in Microsoft Visio. The vulnerabilities could allow remote code execution if a user opens a specially crafted Visio file. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
This security update is rated Important for all supported editions of Microsoft Visio 2003, Microsoft Visio 2007, and Microsoft Visio 2010. The security update addresses the vulnerabilities by correcting the way that Microsoft Visio validates objects in memory when parsing specially crafted Visio files.

此安全更新可解决 Microsoft Visio 中一个公开披露的漏洞。 如果用户打开与特制库文件位于同一网络目录下的合法 Visio 文件,此漏洞可能允许远程执行代码。 成功利用此漏洞的攻击者可以获得与登录用户相同的用户权限。 那些帐户被配置为拥有较少系统用户权限的用户比具有管理用户权限的用户受到的影响要小。
