    Package        : gnome-shell-extension-gsconnect
    CVE ID         : CVE-2025-66270

    It was discovered that missing validation of the device ID during
    handshakes in KDE Connect, a tool to integrate smart phones to a
    desktop, could allow an attacker to impersonate another device.

    The oldstable distribution (bookworm) is not affected.

    For the stable distribution (trixie), this problem has been fixed in
    version 62-1+deb13u1.

    We recommend that you upgrade your gnome-shell-extension-gsconnect packages.

    For the detailed security status of gnome-shell-extension-gsconnect please refer to
