The release of these versions resolves the following security vulnerability:
* AST-2015-003: TLS Certificate Common name NULL byte exploit
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. This potentially allows for a man in the middle attack.
For more information about the details of this vulnerability, please read
security advisory AST-2015-003, which was released at the same time as this
announcement.
