<p>Multiple vulnerabilities have been found in Asterisk:</p>
|
|
|
|
<ul>
|
|
<li>An error in manager.c allows shell access through the MixMonitor
|
|
application, GetVar, or Status (CVE-2012-2414).
|
|
</li>
|
|
<li>An error in chan_skinny.c could cause a heap-based buffer overflow
|
|
(CVE-2012-2415).
|
|
</li>
|
|
<li>An error in chan_sip.c prevents Asterisk from checking if a channel
|
|
exists before connected line updates (CVE-2012-2416).
|
|
</li>
|
|
<li>An error in chan_iax2.c may cause an invalid pointer to be called
|
|
(CVE-2012-2947).
|
|
</li>
|
|
<li>chan_skinny.c contains a NULL pointer dereference (CVE-2012-2948).</li>

</ul>
