The SSH Secure Shell Server from SSH Communications Security
|
|
(www.ssh.com) is a commercial SSH implementation available free for
|
|
non-commercial use.

|
|
The SSH Secure Shell Server contains a format string vulnerability in
|
|
the SFTP code that handles file transfers (scp2 and sftp2). In some
|
|
situations, this code passes the accessed filename to the system log.
|
|
During this operation, an unspecified error could allow uncontrolled
|
|
stack access.

<impact type="normal">
|
|
<p>
|
|
An authenticated system user may be able to exploit this vulnerability
|
|
to bypass command restrictions, or run commands as another user.
|

</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

|
|
This package is currently masked, there is no upgrade path for the
|
|
3.2.x version, and a license must be purchased in order to update to a
|
|
non-vulnerable version. Because of this, we recommend unmerging this
|
|
package:
|
|
</p>
|
|
<code>
|
|
# emerge --ask --verbose --unmerge net-misc/ssh</code>
