    Package : libzstd
    Debian Bug : 982519

    It was discovered that zstd, a compression utility, was vulnerable to
    a race condition: it temporarily exposed, during a very short
    timeframe, a world-readable version of its input even if the original
    file had restrictive permissions.

    For the stable distribution (buster), this problem has been fixed in
    version 1.3.8+dfsg-3+deb10u2.

    We recommend that you upgrade your libzstd packages.

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