Rilasciati Asterisk 13.18.5, 14.7.5, 15.1.5 and 13.18-cert2 (Security)

The Asterisk Development Team would like to announce security releases for Asterisk 13, 14 and 15, and Certified Asterisk 13.18. The available releases are released as versions 13.18.5, 4.7.5, 15.1.5 and 13.18-cert2.

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

The following security vulnerabilities were resolved in these versions:

* AST-2017-014: Crash in PJSIP resource when missing a contact header
A select set of SIP messages create a dialog in Asterisk. Those SIP messages
must contain a contact header. For those messages, if the header was not
present and using the PJSIP channel driver, it would cause Asterisk to crash.
The severity of this vulnerability is somewhat mitigated if authentication is
enabled. If authentication is enabled a user would have to first be authorized
before reaching the crash point.

         CVE Name       

    Description  A select set of SIP messages create a dialog in Asterisk.    
                 Those SIP messages must contain a contact header. For those  
                 messages, if the header was not present and using the PJSIP  
                 channel driver, it would cause Asterisk to crash. The        
                 severity of this vulnerability is somewhat mitigated if      
                 authentication is enabled. If authentication is enabled a    
                 user would have to first be authorized before reaching the   
                 crash point.                                                 

    Resolution  When using the Asterisk PJSIP resource, and one of the SIP    
                messages that create a dialog is received Asterisk now        
                checks to see if the message contains a contact header. If    
                it does not Asterisk now responds with a "400 Missing         
                Contact header".

AST-2017-012: Remote Crash Vulnerability in RTCP Stack

               Asterisk Project Security Advisory - AST-2017-012

          Product         Asterisk

      Advisory Contact    Jcolp AT digium DOT com                             
          CVE Name        

    Description  If a compound RTCP packet is received containing more than   
                 one report (for example a Receiver Report and a Sender       
                 Report) the RTCP stack will incorrectly store report         
                 information outside of allocated memory potentially causing  
                 a crash.                                                     
                                                                              
                 For all versions of Asterisk this vulnerability requires an  
                 active call to be established.                               
                                                                              
                 For versions of Asterisk 13.17.2, 14.6.2, 15.0.0,            
                 13.13-cert6 and greater an additional level of security is   
                 placed upon RTCP packets. If the probation period for        
                 incoming RTP traffic has passed any received RTCP packets    
                 must contain the same SSRC as the RTP traffic. If the RTCP   
                 packets do not then they are dropped. This ensures other     
                 parties can not inject RTCP packets without they themselves  
                 establishing an active call.                                 

    Resolution  The RTCP stack has been changed so the report information is  
                always stored in allocated memory. The provided patches can   
                be applied to the appropriate version or the latest version   
                of Asterisk can be installed to receive the fix.

          CVE Name        

    Description  If the chan_skinny (AKA SCCP protocol) channel driver is     
                 flooded with certain requests it can cause the asterisk      
                 process to use excessive amounts of virtual memory           
                 eventually causing asterisk to stop processing requests of   
                 any kind.                                                    

    Resolution  The chan_skinny driver has been updated to release memory     
                allocations in a correct manner thereby preventing any        
                possiblity of exhaustion.
