If it was recently fixed, which I guess, I should be able to find
something on the daily cvs reports. I haven't read any of them since I
went on VAC, but should be able to read them all in a couple of hours.

I do not have a strong opinion on this, but maybe it should not be
considered as a security issue, just a normal bug; as it is up to the
server settings whether it is possible to overwrite or write anything
outside the path were the file was meant to be unpacked. If it can
bypass the open_basedir restrictions it should then be considered a
security issue, but it is not relevant to Debian either as there's no
support for apps relying on open_basedir.

BUT, if a patch is available and isn't very obtrusive then I see no
reason not to fix it.

Already said I'm going to read all the remaining cvs commit notifs to
try to hunt down the bug fixes.

Just a note on this, although I'll try to hunt down the bug fixes I
can not guarantee anything, as it is well known that some are deeply
