<description>
|
||
<p>It was discovered that Gentoo’s default VDE installation suffered from
|
||
a privilege escalation vulnerability in the init script. This script
|
||
calls an unsafe ‘chown’ command which gives members from “qemu”
|
||
group root privileges.

|
||
<impact type="normal">
|
||
<p>A local attacker could escalate privileges to root.</p>
|
||
</impact>
|
||
<workaround>
|
||
<p>There is no known workaround at this time.</p>
|
||
</workaround>
|
||
<resolution>
|
||
<p>All VDE users should upgrade to the latest version:</p>

<code>
|
||
# emerge --sync
|
||
# emerge --ask --oneshot --verbose ">=net-misc/vde-2.3.2-r4"
