Insecure Flag Handling in mksnap_ffs in FreeBSD 5.1 and 5.2

CVE-2004-0099

mksnap_ffs in FreeBSD 5.1 and 5.2 only sets the snapshot flag when creating a snapshot for a file system, which causes default values for other flags to be used, possibly disabling security-critical settings and allowing a local user to bypass intended access restrictions.
