    Version        : 1:140.10.1esr-1~deb11u1
    CVE ID         : CVE-2026-7320 CVE-2026-7321 CVE-2026-7322 CVE-2026-7323

    Multiple security issues were discovered in Thunderbird, which could
    result in the execution of arbitrary code.

    For Debian 11 bullseye, these problems have been fixed in version

    We recommend that you upgrade your thunderbird packages.
