FreeSWITCH Week in Review (Master Branch) September 12th-18th

Hello, again. This past week in the FreeSWITCH master branch we had 57 commits. The features for this week include: added support for timestamp based counting for jitter buffer in audio mode, added support for X-headers in this 3p mode in mod_sofia, and fine-tuning FEC with repacketization and improved jitter buffer debugging with FEC in mod_opus. And, a security issue was fixed by properly handling malformed json when parsing json!

Join us on Wednesdays at 12:00 CT for some more FreeSWITCH fun! And head over to freeswitch.com to learn more about FreeSWITCH support.

Security Issues:

• FS-8160 Fixed head overflow in json parser, properly handle malformed json when parsing json with \u at the end of a json string. Thank you to Marcello Duarte who discovered and reported this issue.

• FS-8172 [mod_conference] Fixed broken admin controls in verto demo app caused by adding verto_dvar_ prefixed variables to the json status even when we have json status disabled

• FS-8178 [verto_communicator] Define first share device selected by default in settings modal
• FS-8078 [verto_communicator] Fixed display flex in safari
