Linux Kernel AppleTalk内存泄漏远程拒绝服务漏洞

Bugraq ID: 36379
CVE ID：CVE-2009-2903

Linux是一款开放源代码的操作系统。
Linux Kernel AppleTalk处理部分AppleTalk-IP数据帧存在内存泄漏，远程攻击者可以利用漏洞发送大量类似数据帧对系统进行拒绝服务攻击。
当Linux主机加载了appletalk和ipddp模块时，在检查ipddpN设备过程中如果该设备不存在handle_ip_over_ddp() 函数会返回-NODEV给atalk_rcv()函数，之后atalk_rcv()函数会直接将该值返回给调用程序。由于对不能接受的IP-DDP数据帧缺少kfree_skb()调用，向目标主机发送大量畸形AppleTalk-IP数据报就会耗尽所有可用的内核内存，导致拒绝服务攻击。
