CVE-2009-1168 (CNNVD-200907-440)
中文标题:
Cisco IOS畸形BGP报文触发内存崩溃导致拒绝服务漏洞
英文标题:
Cisco IOS 12.0(32)S12 through 12.0(32)S13 and 12.0(33)S3 through 12.0(33)S4, 12.0(32)SY8 through 12....
漏洞描述
中文描述:
Cisco IOS是思科网络设备所使用的互联网操作系统 。 最新版的Cisco IOS Software支持RFC4893规范(BGP Support for Four-octet AS Number Space),在处理特定边界网关协议(BGP)更新时存在两个远程拒绝服务漏洞。 如果BGP更新包含有由多于1000个自治系统组成的AS路径段,第一个漏洞可能导致受影响设备在处理BGP更新时重载。如果2字节AS号BGP speaker包含有由多于1000个自治系统组成的AS路径段的话,受影响的4字节AS号BGP speaker从该2字节AS号BGP speaker接收到BGP更新时设备就可能触发内存破坏而崩溃,显示%%Software-forced reload错误 。 需要满足以下条件才能成功利用这个漏洞: * 受影响的Cisco IOS Software设备是4字节AS号BGP speaker * BGP对等邻居是2字节AS号BGP speaker * BGP对等邻居能够发送一系列大于1000个AS号的BGP更新 这个漏洞在Cisco Bug ID中记录为CSCsy86021。
英文描述:
Cisco IOS 12.0(32)S12 through 12.0(32)S13 and 12.0(33)S3 through 12.0(33)S4, 12.0(32)SY8 through 12.0(32)SY9, 12.2(33)SXI1, 12.2XNC before 12.2(33)XNC2, 12.2XND before 12.2(33)XND1, and 12.4(24)T1; and IOS XE 2.3 through 2.3.1t and 2.4 through 2.4.0; when RFC4893 BGP routing is enabled, allows remote attackers to cause a denial of service (memory corruption and device reload) by using an RFC4271 peer to send an update with a long series of AS numbers, aka Bug ID CSCsy86021.
