CVE-2006-3468

High
Published: Translated: NVD NIST

Summary

A vulnerability in the Linux kernel 2.6.x occurs when both NFS and EXT3 are used together. A remote attacker can send a crafted UDP packet with a V2 lookup procedure specifying a bad file handle (inode number), triggering a file system panic and causing an exported directory to be remounted read-only.

Risk Assessment

An attacker can remotely cause a file system panic and force an exported NFS directory into read-only mode, leading to a denial of service and potential loss of write access for applications.

Recommendation

Update the Linux kernel to a version containing the fix for CVE-2006-3468. If updating is not possible, consider restricting access to the NFS service via firewall or disabling unused exports.
