CVE-2006-4178 (CCN-29170)

Assigned:2006-09-23
Published:2006-09-23
Updated:2018-10-17
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.
