From a higher-up at the UW:
Not that we need another crisis, but it *is* Friday afternoon. ;)
I have not yet been able to get confirming exploit code, but a group
I trust has been discussing a previously undiscussed vulnerability
in sftp in at least OpenSSH prior to 3.6. This vulnerability
has supposedly been known in the underground for two years
(and may be related to the GNU ftp server advisory CERT sent out
I would advise *everyone* using OpenSSH to upgrade immediately
to the latest version, or at least disable sftp (which is on by
default) if you are not using it.
I will send more information when I can confirm things.
