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