OpenSSH is a complete SSH protocol implementation that includes an SFTP
client and server support.
Jan Pechanec discovered that OpenSSH uses a trusted X11 cookie when it
cannot create an untrusted one.
<impact type="low">
An attacker could bypass the SSH client security policy and gain
privileges by causing an X client to be treated as trusted.
There is no known workaround at this time.
All OpenSSH users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/openssh-4.7&quot;</code>
