Jan Pechanec discovered that OpenSSH uses a trusted X11 cookie when it
|
|
cannot create an untrusted one.

<p>
|
|
An attacker could bypass the SSH client security policy and gain
|
|
privileges by causing an X client to be treated as trusted.

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

All OpenSSH users should upgrade to the latest version:

|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/openssh-4.7"</code>
