4.6 · MEDIUMOverview
CVE-2008-1940 is a medium-severity vulnerability affecting grsecurity grsecurity_kernel_patch. It was published on April 25, 2008 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
The RBAC functionality in grsecurity before 2.1.11-2.6.24.5 and 2.1.11-2.4.36.2 does not enforce user_transition_deny and user_transition_allow rules for the (1) sys_setfsuid and (2) sys_setfsgid calls, which allows local users to bypass restrictions for those calls.
Remediation
Check the references section for vendor advisories and patches from grsecurity. Update grsecurity_kernel_patch 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.
