CVE-2016-5104 libimobiledevice: Sockets listening on INADDR_ANY
Last modified: 2016-07-11 09:49:41 EDT
It was found that libimobiledevice and libusbmuxd libraries accidentally bound a listening IPv4 TCP socket to INADDR_ANY instead of INADDR_LOOPBACK.
This socket is used to communicate with services on an iOS device. The impact is accidental exposure of the iOS device to attackers on the local network. The RHEL workstation itself is not exposed, nor is there an easy escalation for attackers to gain access to the host.
Created libimobiledevice tracking bugs for this issue:
Affects: fedora-all [bug 1339990]
Created libusbmuxd tracking bugs for this issue:
Affects: fedora-all [bug 1339991]
libimobiledevice-1.2.0-7.fc24, libusbmuxd-1.0.10-5.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report.
libimobiledevice-1.2.0-7.fc23, libusbmuxd-1.0.10-5.fc23 has been pushed to the Fedora 23 stable repository. If problems still persist, please make note of it in this bug report.
rhel-6/libimobiledevice-0.9.7 unaffected: this version does not bind a socket
rhel-7/libimobiledevice-1.1.5 affected: vuln code is in tools/socket.c
rhel-/usbmuxd affected in libusbmuxd/sock_stuff.c, function create_socket().
Note this package is named differently than in Fedora.
libimobiledevice-1.2.0-7.fc22, libusbmuxd-1.0.10-5.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report.
Lowering the priority of this bug since the rhel host PC is not exposed,
nor does the mobile device's exposure represent a significant attack
vector against the host.
