I'm suspecting that this CVE is already fixed by Richard W.M. Jones.

Yes, you're right.  When I went looking I didn't find the other issue.  Thanks, and sorry for the noise.

patch from Debian to fully correct the issue

Actually, it just came to my attention that this is more than just an absolute path traversal issue, and that using "../" works as well, which the patch noted in bug #487132 fails to address.

I'm going to attach the patch that Debian is planning to use, although updating to 3.0 will also correct the issue.
