<p>Asterisk is an open source telephony engine and toolkit.</p>
<p>Two vulnerabilities have been found in Asterisk:</p>
<li>The "milliwatt_generate()" function in app_milliwatt.c is vulnerable
to a stack overrun (AST-2012-002).
<li>The "ast_parse_digest()" function in utils.c is vulnerable to a
stack-based buffer overflow (AST-2012-003).
<impact type="high">
<p>A remote unauthenticated attacker could execute arbitrary code 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-"
