<p>Asterisk is an open source telephony engine and toolkit.</p>
<p>Multiple vulnerabilities have been found in Asterisk:</p>
<li>An error in manager.c allows shell access through the MixMonitor
application, GetVar, or Status (CVE-2012-2414).
<li>An error in chan_skinny.c could cause a heap-based buffer overflow
<li>An error in chan_sip.c prevents Asterisk from checking if a channel
exists before connected line updates (CVE-2012-2416).
<li>An error in chan_iax2.c may cause an invalid pointer to be called
<li>chan_skinny.c contains a NULL pointer dereference (CVE-2012-2948).</li>
<impact type="normal">
<p>A remote attacker could execute arbitrary code with the privileges of
the process or cause a Denial of Service condition.
<p>There is no known workaround at this time.</p>
<p>All Asterisk users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-misc/asterisk-"
