Summary
The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-05:03.amd64.asc
Insight
Insight
The AMD64 architecture has two mechanisms for permitting processes to access hardware: Kernel code can access hardware directly by reason of its elevated privilege level, while user code can access a subset of hardware determined by a bitmap. The bitmap which determines which hardware can be accessed by unprivileged processes was not initialized properly.
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-05:03.amd64.asc
