<p>It was discovered that Gentoo’s Asterisk ebuild does not properly set
|
|
|
|
|
|
permissions on its data directories. This only affects OpenRC systems, as
|
|
|
|
|
|
the flaw was exploitable via the init script.

<impact type="high">
|

|
|
|
|
<p>A local attacker could escalate privileges.</p>
|
|
|
|
|
|
</impact>
|
|
|
|
|
|
<workaround>
|
|
|
|
|
|
<p>Users should ensure the proper permissions are set as discussed in the
|
|
|
|
|
|
referenced bugs. Do not run /etc/init.d/asterisk checkperms.

|
|

</workaround>

<resolution>
|
|
|
|

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