Upstream won't release the fix... I'm thinking to remove the package.

namazu works without chasen (chasen is optional dependency, namazu work with kakashi or mecab)

Need to drop
- chasen
- ipadic
- ruby-chasen

This sounds like a reasonable approach to me. Do you mind doing it?

I'm not quite sure, but it seems http://git.sourceforge.jp/view?p=chasen-legacy/chasen.git;a=commitdiff;h=05f4be730e9e672bfeae867d9f23055aa3e72ee1 is supposed to be the fix.

Though that doesn't change "end of support" part.

It is pushed by chasen package maintainer @ Debian.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=648359

I'm not sure either. Does it seem to be reviwed now?

[Comment 6 df 2011-12-08 16:19:29 UTC]

patch (chasen244-secfix.diff) has been released officaily.
http://sourceforge.jp/projects/chasen-legacy/releases/?package_id=5861
# same as http://git.sourceforge.jp/view?p=chasen-legacy/chasen.git;a=commitdiff;h=05f4be730e9e672bfeae867d9f23055aa3e72ee1

but it is not changed "end of support" situation as Rafał said probably..

[Comment 7 Naohiro Aota 2011-12-18 06:33:28 UTC]

Added the security fix. Could you test the package? I'll drop the mask then.

[Comment 8 Pacho Ramos 2012-03-18 12:46:20 UTC]

Any updates here? mask entry still tells people this is masked for removal in 30 days...

The security fixed version seems fine. I've dropped the mask.

[Comment 10 df 2012-04-08 10:10:13 UTC]

it's time to arch tests?

packages.g.o is still showing this masked, although I am not sure why, I don't see the mask locally.
