Vulnerability Description
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootp_input() function and could occur while processing a udp packet that is smaller than the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host. The highest threat from this vulnerability is to data confidentiality.

QEMU 缓冲区错误漏洞
Vulnerability Description
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 的 slirp 存在缓冲区错误漏洞，该漏洞源于src/bootp.c 中的 bootp_input() 函数在处理来自来宾的小于 bootp_t 结构（548 字节）大小的 bootp 协议请求的 udp 数据包时，它使用工作 mbuf 缓冲区外部的内存。这可能会导致 10 字节未初始化的堆内存泄漏给来宾。
