The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-07:09.random.asc

Upgrade your system to the appropriate stable release or security branch dated after the correction date https://secure1.securityspace.com/smysecure/catid.html?in=FreeBSD-SA-07:09.random.asc

The random(4) and urandom(4) devices return an endless supply of pseudo-random bytes when read. Cryptographic algorithms often depend on the secrecy of these pseudo-random values for security. Under certain circumstances, a bug in the internal state tracking on the random(4) and urandom(4) devices can be exploited to allow replaying of data distributed during subsequent reads.
