漏洞描述
中文描述:

QEMU（Quick Emulator）是法国法布里斯-贝拉（Fabrice Bellard）个人开发者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存在缓冲区错误漏洞。本地攻击者利用该漏洞通过特制的iSCSI asynchronous I/O ioctl造成拒绝服务（QEMU进程崩溃）或执行任意代码。

英文描述:

Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.
