    Package        : thunderbird
    Version        : 1:140.10.2esr-1~deb11u1
    CVE ID         : CVE-2026-8090 CVE-2026-8092 CVE-2026-8094

    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
    1:140.10.2esr-1~deb11u1.

    We recommend that you upgrade your thunderbird packages.

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

    Further information about Debian LTS security advisories, how to apply
    these updates to your system and frequently asked questions can be
