Title: QEMU 'ne2000_buffer_full()'拒绝服务漏洞

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，该漏洞由于程序处理特定的数据包时，hw/net/ne2000.c文件的‘ne2000_buffer_full()’函数中存在错误。当程序支持NE2000 NIC仿真时，本地攻击者利用该漏洞造成拒绝服务（无限循环），或获取提升的权限。

Severity: 低

Summary

The ne2000_receive function in the NE2000 NIC emulation support (hw/net/ne2000.c) in QEMU before 2.5.1 allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via crafted values for the PSTART and PSTOP registers, involving ring buffer control.
