CVE-2017-16672 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-16672):
  An issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before
  14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before
  13.13-cert7. 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.
  Eventually Asterisk can run out of memory and crash.

CVE-2017-16671 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-16671):
  A Buffer Overflow issue was discovered in Asterisk Open Source 13 before
  13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13
  before 13.13-cert7. 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. NOTE:
  this is different from CVE-2017-7617, which was only about the Party A
  buffer.
