Description:	Because an outdated library could contain a security issue, I am asking to display the version of the bundled library, for example, at the start of Asterisk (or even better via a command on the command-line interface; CLI). Actually, there have been security issues in the Opus Codec library, [in the past …|https://www.opus-codec.org/news/] Actually, actually, this issue rose from a different perspective, classifying this issue not as a feature request but a software bug. Although, I was able to overwrite it via the configuration file {{codecs.conf}}, I do not consider that an easy workaround – therefore, the severity Major. Anyway, depending on the actual cause, it could be anything from a feature request to a security bug. While debugging (another case with) the [ToC byte|https://tools.ietf.org/html/rfc6716#section-3.1] in the RTP media stream of the audio codec Opus Codec, I noticed, the Digium/Sangoma module sends Super Wideband (swb) although the caller stated to support just Wideband (wb) in its SDP. This codec module is closed source and comes with a bundled libopus. That codec module has not been updated since the [year 2017|https://downloads.digium.com/pub/telephony/codec_opus/]. Therefore, the bundled libopus cannot be the [current version 1.3.1|https://archive.mozilla.org/pub/opus/]. I cross-checked with ‘my’ open-source Opus Codec module, which can be linked to any libopus. I went for an older version of libopus and was able to duplicate the symptom. Therefore, I guess, the cause is the old bundled libopus. I know, this was reported back in the year 2019 [already|https://community.asterisk.org/t/81919]. However, because that did not create an issue report here in Jira, I guess, that report was classified not as software bug but feature request. Because of those two reasons, I would like to know the version of the bundled libopus, to double-check (if there is a security concern and/or whether the outdated libopus might cause my interoperability issue).

By: Joshua C. Colp (jcolp) 2021-08-16 04:45:28.718-0500 The version in it for libopus is 1.2.1 while opusfile is 0.9. I have updated the internal issue accordingly. By: Alexander Traud (traud) 2021-08-16 07:20:54.694-0500 Not aware of any security issues with libopus 1.2.1 or opusfile 0.9. :) Consequently, this here is just an interoperability issue report.
