The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-05:08.kmem.asc

Insight

Insight

In many parts of the FreeBSD kernel, names (of mount points, devices, files, etc.) are manipulated as NULL-terminated strings, but are provided to applications within fixed-length buffers. In several places, variable-length strings were copied into fixed-length buffers without zeroing the unused portion of the buffer.

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-05:08.kmem.asc
