Summary

The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-10:08.bzip2.asc

Insight

Insight

The bzip2/bunzip2 utilities and the libbz2 library compress and decompress files using an algorithm based on the Burrows-Wheeler transform. They are generally slower than Lempel-Ziv compressors such as gzip, but usually provide a greater compression ratio. When decompressing data, the run-length encoded values are not adequately sanity-checked, allowing for an integer overflow.

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-10:08.bzip2.asc
