The remote Fedora host is missing a security update.


The Asterisk Development Team has announced security releases for Certified Asterisk 1.8.28, 11.6, and 13.1 and Asterisk 1.8, 11, 12, and 13. The available security releases are released as versions 1.8.28.cert-5,, 11.6-cert11, 11.17.1, 12.8.2, 13.1-cert2, and 13.3.2.

These releases are available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/releases

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.
