+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.

+BugDebian: http://bugs.debian.org/700914
+Description: This patch was created by oCert according to
+  http://www.ocert.org/advisories/ocert-2008-014.html
+ and can be downloaded from
+  http://www.ocert.org/analysis/2008-014/wordnet.patch
+ Unfortunately the original patch had a problem which
+ caused 'wordnet test -synsn' to fail.  The critical
+ part of the patch was removed from the whole patch
+ set and is moved to 51_overflows_memcpy.patch which
+ uses memcpy instead of the formerly used strcpy.
