Hi,

the following vulnerability was published for asterisk.

CVE-2017-16672[0]:
| 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.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
