Description

Linux kernel 2.6.x, when using both NFS and EXT3, allows remote attackers to cause a denial of service (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), which triggers an error and causes an exported directory to be remounted read-only.

Affected products

Linux kernel: 2.6.0, 2.6.0-test1, 2.6.0-test10, 2.6.0-test11, 2.6.0-test2, 2.6.0-test3 (+167)
