Debian has released security updates for two Debian GNU/Linux 11 (Bullseye) LTS packages: tryton-server and sogo. Tryton-server was vulnerable to information disclosure, but this issue has been fixed in version 5.0.33-2+deb11u4. Sogo, on the other hand, had a Cross-Site Scripting (XSS) vulnerability that allowed arbitrary JavaScript to be executed via the "userName" parameter, but this problem was addressed in version 5.0.1-4+deb11u2. Both packages are recommended to be upgraded to their respective fixed versions to ensure system security.
