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

| <description> |
| <p> |
| 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. |
| </p> |
| </description> |
| <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. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| 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> |
