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:
