Fix CVE-2008-2149: buffer overflows by limiting the length of the string in sprintf
format string
Closes: #481186 (CVE-2008-2149)
Please note: The WordNet code contains several other occurences of potentially
exploitable functions like strcpy()/strcat()/...  and so even if there are no
known exploits the code needs a full security audit.
