Package        : man-db

A previous man-db update (DSA-364-1) fixed buffer overruns in ult_src, a
part of the "mandb" command that finds the canonical source file for
each man page.  However, this update introduced an error in the routine
that resolves hardlinks: depending on the filenames of hardlinked man
pages, that routine might itself overrun allocated memory, causing a
segmentation fault.

For the current stable distribution (woody), this problem has been fixed
in version 2.3.20-18.woody.4.

For the unstable distribution (sid), this problem has been fixed in
version 2.4.1-13.

We recommend that you update your man-db package.

Upgrade Instructions
- --------------------

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

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

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