    Version        : 1.0.4-4+deb11u1
    CVE ID         : CVE-2025-9287
    Debian Bug     : 1111772

    Incomplete type checks when validating input have been fixed in
    node-cipher-base, an abstract Node.js base class for crypto-streams.

    For Debian 11 bullseye, this problem has been fixed in version
    1.0.4-4+deb11u1.

    We recommend that you upgrade your node-cipher-base packages.

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