Asterisk may crash when processing an incoming REGISTER request if that REGISTER contains a Contact header with a lengthy URI. This crash will only happen for requests that pass authentication. Unauthenticated REGISTER requests will not result in a crash occurring. This vulnerability only affects Asterisk when using PJSIP as its SIP stack. The chan_sip module does not have this problem.
