What is Greenlight?

Greenlight 3.9.1 fixes a critical upload flaw and tells admins to rotate secrets.

Greenlight, the BigBlueButton web frontend, released 3.9.1 on Nov 5 to fix a critical flaw: through a Rails Active Storage issue, a user able to upload an avatar or presentation could read or write files on the server. The fix comes from Rails 8.0.5.2's stricter ImageMagick policy, and instances storing uploads on local disk are told to rotate SECRET_KEY_BASE, database, BigBlueButton and other credentials.

What is TrueConf?

TrueConf takes its on-prem pitch to GITEX after a month of PHP patches.

A critical PHP vulnerability in TrueConf Server's web service (PHP2Shell, all versions through 5.5.7) drove a security advisory, the 5.5.8 release and matching 5.4.11 and 5.3.11 updates. TrueConf Room gained better calendar-connector handling. Since then the feed is event marketing, with recaps of ADIPEC and plans for GITEX GLOBAL.

2.5

Greenlight 3.9.1 fixes a critical upload flaw and tells admins to rotate secrets.

◆ Current state

Greenlight, the BigBlueButton web frontend, released 3.9.1 on Nov 5 to fix a critical flaw: through a Rails Active Storage issue, a user able to upload an avatar or presentation could read or write files on the server. The fix comes from Rails 8.0.5.2's stricter ImageMagick policy, and instances storing uploads on local disk are told to rotate SECRET_KEY_BASE, database, BigBlueButton and other credentials.

◆ Where it's heading

The project remains in security maintenance: gem updates, a breaking URL_HOST requirement in 3.9.0 and now an urgent patch. Feature work has been rare since the invitation changes in April.

◆ Prediction

Expect more dependency-driven security releases; new features look unlikely from the recent pattern.

5.0

TrueConf takes its on-prem pitch to GITEX after a month of PHP patches.

◆ Current state

A critical PHP vulnerability in TrueConf Server's web service (PHP2Shell, all versions through 5.5.7) drove a security advisory, the 5.5.8 release and matching 5.4.11 and 5.3.11 updates. TrueConf Room gained better calendar-connector handling. Since then the feed is event marketing, with recaps of ADIPEC and plans for GITEX GLOBAL.

◆ Where it's heading

TrueConf sells on-premises communications to regulated and industrial customers, and recent releases are mostly about keeping several supported server versions patched. Feature work, such as quick polls and chatbot buttons in 5.5.6, comes in smaller monthly steps.

◆ Prediction

Expect the November security update and a 5.5.9 server release, with feature work resuming in the 5.5 line.
