[原文]Multiple integer signedness errors in the BGP dissector in Ethereal 0.9.7 and earlier allow remote attackers to cause a denial of service (infinite loop) via malformed messages.


[CNNVD]Ethereal BGP解析器无限循环远程拒绝服务攻击漏洞(CNNVD-200212-044)

        
        Ethereal是一款免费开放源代码的网络协议分析程序,可使用在Unix和Windows操作系统下。
        Ethereal中的BGP解析器在消息长度为负值时处理不正确,远程攻击者利用这个漏洞进行发送恶意包使Ethereal崩溃,导致拒绝服务攻击。
        Ethereal中的BGP解析器用于对边界网关协议(BGP)进行解码。由于对消息包长度负正处理不匹配,攻击者可以构建包含长度为负值的的BGP消息包并提交给有Ethereal监听的网络中,可导致Ethereal崩溃。
