Created attachment 72884 [details, diff] lynx-2.8.5-rel5.patch Cumulative patch from vanilla 2.8.5 to rel5. - 010_all_lynx-2.8.5-CAN-2005-3120.patch: included almost verbatim - 011_all_lynx-2.8.5-CVE-2005-2929.patch: the first part is included, but the two lines added to LYGetFile.c are not (they are probably not necessary). I think it is safe to make a new release (-r3?) syncing up to this version.
Added to portage. lynx-2.8.5-r3 will build lynx up to rel5.
