Vulnerability from fkie_nvd - Published: 2006-09-26 02:07 - Updated: 2026-06-16 22:28
Severity
Summary
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.
