Looks like there are a few issues here:

2011-01-16  19:31  Reuben Thomas <rrt at>
     * Fix two potential buffer overruns in apprentice_list.

2010-09-20  15:24  Reuben Thomas <rrt at>
     * Minor security fix to softmagic.c (don't use untrusted
       string as printf format).

I have not looked at them in more depth to see how much of a problem they are,
or when they were introduced (in order to know which versions are affected),

I'm cc'ing Christos to see if he can perhaps enlighten us.
