Linux内核Ext3无效索引节点序号拒绝服务攻击漏洞

Secunia Advisory:SA21369 Linux内核被报告一个漏洞，该漏洞可被恶意用户操作进行拒绝服务攻击Denial of Service。 该漏洞是由处理一个无效索引节点序号（inode number）时ext3内的一个错误引起的。盖漏洞可被操作发送一个特殊处理的带有V2程序例如 V2LOOKUP的NFS请求使其列入无效索引节点序号。 成功操作会致使输出目录被重置为只读。 该漏洞已经在版本2.6.14.4、2.6.17.6和2.6.17.7中被证实。其他版本可能同样被影响。 Linux Kernel 2.6.x 仅同意信任用户访问受影响系统。...
