Overview
CVE-2007-3722 is a low-severity vulnerability affecting freebsd freebsd. It was published on July 12, 2007 and has a CVSS 2.0 base score of 2.1 (LOW).
This vulnerability has a CVSS 2.0 base score of 2.1, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical description
The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
Remediation
Check the references section for vendor advisories and patches from freebsd. Update freebsd 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.
