Hi,
The following vulnerability was published for asterisk.
CVE-2020-28242[0]:
| An issue was discovered in Asterisk Open Source 13.x before 13.37.1,
| 16.x before 16.14.1, 17.x before 17.8.1, and 18.x before 18.0.1 and
| Certified Asterisk before 16.8-cert5. If Asterisk is challenged on an
| outbound INVITE and the nonce is changed in each response, Asterisk
| will continually send INVITEs in a loop. This causes Asterisk to
| consume more and more memory since the transaction will never
| terminate (even if the call is hung up), ultimately leading to a
| restart or shutdown of Asterisk. Outbound authentication must be
| configured on the endpoint for this to occur.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
