The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200704-01
(Asterisk: Two SIP Denial of Service vulnerabilities)
The Madynes research team at INRIA has discovered that Asterisk
contains a null pointer dereferencing error in the SIP channel when
handling INVITE messages. Furthermore qwerty1979 discovered that
Asterisk 1.2.x fails to properly handle SIP responses with return code
A remote attacker could cause an Asterisk server listening for SIP
messages to crash by sending a specially crafted SIP message or
answering with a 0 return code.
There is no known workaround at this time.

All Asterisk users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose net-misc/asterisk
Note: Asterisk 1.0.x is no longer supported upstream so users should
consider upgrading to Asterisk 1.2.x.
