Updated libplist packages fix security vulnerability

The base64decode function in libplist allowed attackers to obtain sensitive information from process memory or cause a denial of service (buffer over-read) via split encoded Apple Property List data (CVE-2017-5209). The main function in plistutil.c in libimobiledevice libplist allowed attackers to obtain sensitive information from process memory or cause a denial of service (buffer over-read) via Apple Property List data that is too short (CVE-2017-5545). A heap-buffer overflow in parse_dict_node could cause a segmentation fault (CVE-2017-5834). Malicious crafted file could cause libplist to allocate large amounts of memory and consume lots of CPU because of a memory allocation error (CVE-2017-5835). A type inconsistency in bplist.c could cause the application to crash (CVE-2017-5836). Crafted plist file could lead to Heap-buffer overflow (CVE-2017-6435). Integer overflow in parse_string_node (CVE-2017-6436). The base64encode function in base64.c allows local users to cause denial of service (out-of-bounds read) via a crafted plist file (CVE-2017-6437). Heap-based buffer overflow in the parse_unicode_node function (CVE-2017-6438). Heap-based buffer overflow in the parse_string_node function (CVE-2017-6439). Ensure that sanity checks work on 32-bit platforms (CVE-2017-6440). Add some safety checks, backported from upstream (CVE-2017-7982). The gvfs, ifuse, kodi, libgpod, libimobiledevice, upower, and usbmuxd packages have been rebuilt for the updated libplist.
