Overview

CVE-2007-0004 is a low-severity vulnerability affecting redhat enterprise_linux. It was published on September 18, 2007 and has a CVSS 2.0 base score of 1.9 (LOW).

This vulnerability has a CVSS 2.0 base score of 1.9, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

The NFS client implementation in the kernel in Red Hat Enterprise Linux (RHEL) 3, when a filesystem is mounted with the noacl option, checks permissions for the open system call via vfs_permission (mode bits) data rather than an NFS ACCESS call to the server, which allows local client processes to obtain a false success status from open calls that the server would deny, and possibly obtain sensitive information about file permissions on the server, as demonstrated in a root_squash environment. NOTE: it is uncertain whether any scenarios involving this issue cross privilege boundaries.

Remediation

Check the references section for vendor advisories and patches from redhat. Update enterprise_linux to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
