[原文]Integer overflow in IEEE 802.11 network subsystem (ieee80211_ioctl.c) in FreeBSD before 6.0-STABLE, while scanning for wireless networks, allows remote attackers to execute arbitrary code by broadcasting crafted (1) beacon or (2) probe response frames.


[CNNVD]FreeBSD IEEE 802.11网络子系统远程溢出漏洞(CNNVD-200601-234)

        FreeBSD的IEEE 802.11网络子系统可为无线联网实现协议协商。
        FreeBSD的IEEE 802.11在处理协议协商时存在漏洞,远程攻击者可能利用此漏洞在主机上执行任意指令。在扫描已有的无线网络时,如果处理了被破坏的IEEE 802.11信标或探测响应帧的话就会出现整数溢出,导致帧溢出缓冲区。能够广播特制信标或探测响应帧的攻击者可以在任何扫描无线网络的系统上以FreeBSD Kernel权限执行任意代码。

22537
FreeBSD net80211 Module IEEE 802.11 Probe Response Overflow
Remote / Network Access Input Manipulation
Loss of Integrity

- 漏洞描述

A remote overflow exists in FreeBSD. With a specially crafted request beacon or probe response frame, a malicious attacker may be able to execute arbitrary code within the context of the FreeBSD kernel on any system scanning for wireless networks. This flaw may lead to a loss of integrity.

FreeBSD IEEE 802.11 Network Subsystem Remote Buffer Overflow Vulnerability

Karl Janmar reported this issue to the vendor.

- 受影响的程序版本

FreeBSD FreeBSD 6.0 -STABLE
FreeBSD FreeBSD 6.0 -RELEASE

- 漏洞讨论

FreeBSD is susceptible to a remote, kernel-level buffer overflow vulnerability. This issue is due to a failure of the kernel to properly bounds check user-supplied network data prior to copying it to an insufficiently sized memory buffer.

This issue allows remote attackers to execute arbitrary machine code in the context of the affected kernel, facilitating the complete compromise of affected computers. As this issue is present in a low-level network subsystem, it is likely exploitable even if the host is blocking packets with a host-based packet filter.
