DESCRIPTION:
FreeBSD has issued an update for mountd. This fixes a security issue,
which can be exploited by malicious people to bypass certain security
restrictions.
The security issue is caused due to an error within the handling of
"-network" definitions using the CIDR notion with a certain prefix
length when parsing the exports table, which can result in an
incorrect network mask being used to enforce ACL restrictions.
Successful exploitation requires that a prefix length that is not a
multiple of 8 is used.
SOLUTION:
Update FreeBSD or apply patch.
