Integer signedness error in the i386_set_ldt call in FreeBSD 5.5, and possibly earlier versions down to 5.2, allows local users to cause a denial of service (crash) via unspecified arguments that use negative signed integers to cause the bzero function to be called with a large length parameter, a different vulnerability than CVE-2006-4172.

Impact Subscore: 6.9
Exploitability Subscore: 3.9
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: Low
