Title: QEMU USB Net NDIS整数溢出漏洞
Description:
QEMU是法国程序员法布里斯-贝拉（Fabrice Bellard）所研发的一套模拟处理器软件。该软件具有速度快、跨平台等特点。
QEMU中存在安全漏洞，该漏洞由于/hw/usb/dev-network.c文件的‘rndis_query_response()’、‘rndis_set_response()’及‘usb_net_handle_dataout()’函数中存在整数溢出错误。当程序使用USB Net设备模拟器时，本地攻击者利用该漏洞获取敏感信息或造成拒绝服务（进程崩溃）。
Severity: 低
Patch Name: QEMU USB Net NDIS整数溢出漏洞的补丁
