CVE:CVE-2009-0322
CNNVD:CNNVD-200901-418
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。
Linux Kernel的drivers/firmware/dell_rbu.c文件中的read_rbu_image_type()和read_rbu_packet_size()函数中存在拒绝服务漏洞。如果上述函数从sys/devices/platform/dell_rbu/image_type或/sys/devices/platform/dell_rbu/packet_size读取了0字节的话，就会导致系统崩溃。
solution:Upgrade linux linux_kernel to a higher version than 2.6.27.13,2.6.28.2,and avoid the version (,2.6.27.13),[2.6.28,2.6.28.2); Upgrade debian debian_linux to a higher version than 4.0,5.0,and avoid the version 4.0,5.0; Upgrade canonical ubuntu_linux to a higher version than 7.10,8.04,8.10,and avoid the version 7.10,8.04,8.10
