[原文]Memory leak in Juniper JUNOS Packet Forwarding Engine (PFE) allows remote attackers to cause a denial of service (memory exhaustion and device reboot) via certain IPv6 packets.


[CNNVD]Juniper JUNOS包转发引擎IPv6远程拒绝服务漏洞(CNNVD-200412-047)

        
        Juniper JUNOS是网络操作系统,提供卓越的故障恢复能力并确保能够简单地集成IPv6。
        Juniper JUNOS在处理部分IPV6包时存在问题,远程攻击者可以利用这个漏洞对运行JUNOS设备的路由器进行拒绝服务攻击。
        当一个入站IPv6包需要路由器生成一个ICMPv6应答时,应答可能不产生,而且缓冲区包含原始包不释放,最后包转发引擎CPU会消耗大量内存而导致重新启动。所有JUNOS Release 6.x或2004-02-24之后运行M-series和T-series路由平台存在此漏洞。

- 漏洞讨论

Juniper routers running the JUNOS operating system are reported prone to a denial of service vulnerability due to memory exhaustion. An attacker can cause a persistent denial of service condition by repeatedly sending certain IPv6 packets to a router.

This issue affects the JUNOS Packet Forwarding Engine IPv6 branch released after February 24, 2004. All Juniper Networks M-series and T-series routing platforms with IPv6 support are also prone to this issue.

- 漏洞利用

Currently we are not aware of any exploits for this issue. If you feel we are in error or are aware of more recent information, please mail us at: vuldb@securityfocus.com <mailto:vuldb@securityfocus.com>.

- 解决方案

Juniper Networks has reported that all JUNOS software built on or after June 21, 2004 includes the corrected code. Customers are advised to contact the vendor to obtain fixes.
