According to the version in its SIP banner, the version of Asterisk running on the remote host is potentially affected by multiple denial of service vulnerabilities : - If a remote user sends a SIP packet with a NULL, Asterisk reads data past the NULL even though the buffer is actually truncated...

FreeBSD : Asterisk -- multiple vulnerabilities (40544e8c-9f7b-11e0-9bec-6c626dd55a41)

The Asterisk Development Team reports : AST-2011-008: If a remote user sends a SIP packet containing a NULL, Asterisk assumes available data extends past the null to the end of the packet when the buffer is actually truncated when copied. This causes SIP header parsing to modify data past the end...
