The SIP channel driver in Asterisk Open Source 1.4.22, 1.4.23, and; 1.6.0 before; 1.6.1 before; and Asterisk
Business Edition C.2.3, with the pedantic option enabled, allows
remote authenticated users to cause a denial of service (crash) via a
SIP INVITE request without any headers, which triggers a NULL pointer
dereference in the (1) sip_uri_headers_cmp and (2) sip_uri_params_cmp
