         CVE Name       

    Description  A memory leak occurs when an Asterisk pjsip session object   
                 is created and that call gets rejected before the session    
                 itself is fully established. When this happens the session   
                 object never gets destroyed.                                 

    Resolution  Asterisk now releases the session object and all associated   
                memory when a call gets rejected.

         CVE Name       

    Description  No size checking is done when setting the user field for     
                 Party B on a CDR. Thus, it is possible for someone to use    
                 an arbitrarily large string and write past the end of the    
                 user field storage buffer. The earlier AST-2017-001          
                 advisory for the CDR user field overflow was for the Party   
                 A buffer.                                                    
                                                                              
                 This currently affects any system using CDR's that also      
                 make use of the following:                                   
                                                                              
                 * The 'X-ClientCode' header within a SIP INFO message when   
                 using chan_sip and                                           
                                                                              
                 the 'useclientcode' option is enabled (note, it's disabled   
                 by default).                                                 
                                                                              
                 * The CDR dialplan function executed from AMI when setting   
                 the user field.                                              
                                                                              
                 * The AMI Monitor action when using a long file name/path.   

    Resolution  The CDR engine now only copies up to the maximum allowed      
                characters into the user field. Any characters outside the    
                maximum are truncated.

    Description  By carefully crafting invalid values in the Cseq and the     
                 Via header port, pjproject’s packet parsing code can create  
                 strings larger than the buffer allocated to hold them. This  
                 will usually cause Asterisk to crash immediately. The        
                 packets do not have to be authenticated.                     

    Resolution  Stricter validation is now done on strings that represent     
                numeric values before they are converted to intrinsic types.  
                Invalid values now cause packet processing to stop and error  
                messages to be emitted.
