Description Adam Mariš 2016-05-26 10:04:41 UTC

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.

Upstream patches:

libusbmuxd: https://github.com/libimobiledevice/libusbmuxd/commit/4397b3376dc4e4cb1c991d0aed61ce6482614196

libimobiledevice: https://github.com/libimobiledevice/libimobiledevice/commit/df1f5c4d70d0c19ad40072f5246ca457e7f9849e

Comment 6 Doran Moppert 2016-05-31 03:45:47 UTC

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

Comment 7 Doran Moppert 2016-05-31 05:47:09 UTC

rhel-[67]/usbmuxd affected in libusbmuxd/sock_stuff.c, function create_socket().

Note this package is named differently than in Fedora.

Comment 9 Fedora Update System 2016-06-01 20:22:50 UTC

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.

Comment 10 Doran Moppert 2016-06-07 02:59:05 UTC

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.
