Ubuntu 4.10 / 5.04 : openssh vulnerability (USN-209-1)

medium Nessus Plugin ID 20626

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
