Patch Name

D-Link DIR-665缓冲区溢出漏洞的补丁

Patch Description

D-Link DIR-665是一款高性能无线路由器，属于D-Link的Xtreme N系列产品，主要面向需要高速网络连接的家庭和中小企业用户。 D-Link DIR-665在固件1.00版本中存在缓冲区溢出漏洞。该漏洞源于设备在解析HTTP POST请求时，未对用户输入的Content-Length字段进行有效验证，直接将其作为参数传递给固定大小的栈缓冲区进行数据读取操作。攻击者可通过构造包含超长负载的POST请求，触发函数sub_AC78中固定大小栈缓冲区的溢出，覆盖返回地址或关键内存数据，最终导致远程代码执行或服务崩溃。目前，供应商发布了安全公告及相关补丁信息，修复了此漏洞。
