LastChanged: Tue, 26 Feb 2013 20:40:25 +0100
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.
