USN-209-1: SSH server vulnerability
===========================================================
Ubuntu Security Notice USN-209-1 October 17, 2005
openssh vulnerability
CAN-2005-2798
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
The following packages are affected:
openssh-server
The problem can be corrected by upgrading the affected package to
version 1:3.8.1p1-11ubuntu3.2 (for Ubuntu 4.10), or 1:3.9p1-1ubuntu2.1
(for Ubuntu 5.04). In general, a standard system upgrade is
sufficient to effect the necessary changes.
Details follow:
An information disclosure vulnerability has been found in the SSH
server. When the GSSAPIAuthentication option was enabled, the SSH
server could send GSSAPI credentials even to users who attempted to
log in with a method other than GSSAPI. This could inadvertently
expose these credentials to an untrusted user.
Please note that this does not affect the default configuration of the
SSH server.
