Oh. Which security problem are you talking about?

Ugh? How did that happen?
Where is the second one? I only see 2.1.5-8sarge3 in stable but only
2.1.5-8sarge2 in the security archive.

Apparently it has been installed in the archive.

Umh? But where is it? I don't have it either. I have recorded the
patch to fix this vulnerability, though. It's attached.

I found a trace. Apparently this problem has been considered not
exploitable later, and hence the issue was disregarded. The
researcher was Karl Chen. He suggested to file a normal bug then. If
that has happened, you should have (had) it in your bug list.

This is an interesting screwup...

I'll forward you the mails wrt this issue.
Guess we didn't contact you earlier because it became a non-issue.

Imho, it's more useful to upload 2.1.5-8sarge4 and only bump the
version number to get the new version built for all architectures into
Linux - the choice of a GNU generation.
Please always Cc to me when replying to me on the lists.
