    rLottie is a platform independent C++ library for rendering vector-based
    animations and art. Its format is used by Telegram Desktop, fast and secure
    messaging application, which is the only reverse dependency in Debian.

    Several flaws caused by C++ undefined behavior in this library were recently
    reported as CVE issues. The new update addresses six of them as well as
    backports other crash fixes.

    For Debian 11 bullseye, these problems have been fixed in version
    0.1+dfsg-2+deb11u2.

    We recommend that you upgrade your rlottie packages.

    For the detailed security status of rlottie please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/rlottie
