Description Andrej Nemec 2016-04-15 07:25:04 UTC
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.
