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.
