Medium Nessus Plugin ID 82650
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe Asterisk project reports :
When Asterisk registers to a SIP TLS device and and verifies the server, Asterisk will accept signed certificates that match a common name other than the one Asterisk is expecting if the signed certificate has a common name containing a null byte after the portion of the common name that Asterisk expected. For example, if Asterisk is trying to register to www.domain.com, Asterisk will accept certificates of the form www.domain.com\x00www.someotherdomain.com
