    Package        : usbmuxd
    CVE ID         : CVE-2025-66004
    Debian Bug     : 1122507

    A path traversal vulnerability was discovered in usbmuxd, a multiplexor daemon
    used to coordinate USB connections from and to Apple devices (iPhone, iPad,
    iPod).

    Exploiting this vulnerability enables an unprivileged user to create and delete
    files named `*.plist` (and, in some cases, arbitrarily named) as the user
    running the daemon (`usbmux` by default).

    For the oldstable distribution (bookworm), this problem has been fixed
    in version 1.1.1-2+deb12u1.

    For the stable distribution (trixie), this problem has been fixed in
    version 1.1.1-6+deb13u1.

    We recommend that you upgrade your usbmuxd packages.

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