Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

QEMU（又名Quick Emulator）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中的hw/net/net_tx_pkt.c文件的‘net_tx_pkt_init’函数存在整数溢出漏洞,该漏洞源于最大的储存残片计数可触发未受监测的乘法运算和空指针逆向。本地访客端操作系统的攻击者可利用该漏洞造成拒绝服务漏洞（QEMU进程崩溃）。
