Hi,
The following vulnerability was published for asterisk.
CVE-2021-26717[0]:
| An issue was discovered in Sangoma Asterisk 16.x before 16.16.1, 17.x
| before 17.9.2, and 18.x before 18.2.1 and Certified Asterisk before
| 16.8-cert6. When re-negotiating for T.38, if the initial remote
| response was delayed just enough, Asterisk would send both audio and
| T.38 in the SDP. If this happened, and the remote responded with a
| declined T.38 stream, then Asterisk would crash.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
