Critical Debian advisory DSA-028-1 warns of a format string issue; local exploit risk requires immediate action.
Styx has reported that the program `man' mistakenly passes maliciousstrings through routines that were not meant to use them as format strings.

Summary

Styx has reported that the program `man' mistakenly passes malicious
strings (i.e. containing format characters) through routines that were
not meant to use them as format strings. Since this could cause a
segmentation fault and privileges were not dropped it may lead to an
exploit for the 'man' user.

We recommend you upgrade your man-db package immediately.

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.
