漏洞描述

Microsoft Data Access Components是一款微软数据库访问组件。Microsoft Data Access Components处理部分ODBC API的DSN(Data Source Name)参数时存在错误，攻击者可以利用漏洞进行缓冲区溢出攻击。odbc32.dll组件中的SQLConnectW调用存在缺陷。当计算用户提供的szDSN大小时，传递给lstrlenW的调用结果用于与SQL_MAX_DSN_LENGTH的符号对比以验证目的缓冲区大小，此值之后用于把用户提供的数据拷贝到固定长度的栈缓冲区中，恶意szDSN长度可用于利用符号错误执行任意代码。
