CVE-2009-3286
4.6 · MEDIUMOverview
CVE-2009-3286 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 22, 2009 and has a CVSS 2.0 base score of 4.6 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 4.6, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel 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.
