    Package        : smb4k
    CVE ID         : CVE-2025-66002 CVE-2025-66003
    Debian Bug     : 1122381

    Two vulnerabilities were discovered in smb4k, a KDE desktop utility
    which allows unprivileged mounting of Samba/CIFS network shares, which
    may result in local denial of service or local privilege escalation.

    For the stable distribution (trixie), these problems have been fixed in
    version 4.0.0-1+deb13u1.

    We recommend that you upgrade your smb4k packages.

    For the detailed security status of smb4k please refer to its security
    tracker page at:
    https://security-tracker.debian.org/tracker/smb4k
