<p>KAuth provides a convenient, system-integrated way to offload actions
|
|
that need to be performed as a privileged user (root, for example) to
|
|
small (hopefully secure) helper utilities.

<description>
|
|
<p>KAuth and KDELibs contains a logic flaw in which the service invoking
|
|
D-Bus is not properly checked. This allows spoofing the identity of the
|
|
caller and with some carefully crafted calls can lead to gaining root
|
|
from an unprivileged account.
|
|

|
<impact type="high">
|
|
<p>A local attacker could spoof the identity of the caller invoking D-Bus,
|
|
possibly resulting in gaining privileges.

|
</p>

</impact>

<workaround>
|

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

<resolution>

<p>All KAuth users should upgrade to the latest version:</p>

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=kde-frameworks/kauth-5.29.0-r1"

<p>All KDELibs users should upgrade to the latest version:</p>
