Description:
James McKenzie has reported a vulnerability in Linux Kernel, which can be exploited by malicious users to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in ext3 when handling an invalid inode number. This can be exploited by sending a specially crafted NFS request with a V2 procedure (e.g. V2_LOOKUP) that specifies an invalid inode number.
Successful exploitation causes the exported directory to be remounted read-only.
The vulnerability has been reported in versions 2.6.14.4, 2.6.17.6, and 2.6.17.7. Other versions may also be affected.
