    Package        : dlt-daemon
    Version        : 2.18.0-1+deb10u2
    CVE ID         : CVE-2022-39836 CVE-2022-39837 CVE-2023-26257 CVE-2023-36321

    Several flaws were discovered in dlt-daemon, a Diagnostic Log and Trace logging
    daemon. Buffer overflows and memory leaks may lead to a denial of service or
    other unspecified impact.

    For Debian 10 buster, these problems have been fixed in version
    2.18.0-1+deb10u2.

    We recommend that you upgrade your dlt-daemon packages.

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