"This update for libplist fixes the following security issues :

  - CVE-2017-5545: 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. (bsc#1021610).

  - CVE-2017-5209: The base64decode function in base64.c in
    libimobiledevice libplist through 1.12 allows attackers
    to obtain sensitive information from process memory or
    cause a denial of service (buffer over-read) via split
    encoded Apple Property List data. (bsc#1019531)

  - CVE-2017-5836: A type inconsistency in bplist.c was
    fixed. (bsc#1023807)

  - CVE-2017-5835: A memory allocation error leading to DoS
    was fixed. (bsc#1023822)

  - CVE-2017-5834: A heap-buffer overflow in parse_dict_node
    was fixed (bsc#1023848)

  - CVE-2017-7982: Denial of service (heap-based buffer
    over-read and application crash) via a crafted plist
    file (bsc#1035312)

  - CVE-2017-6440: A specially crafted plist file could lead
    to denial of service (bsc#1029631)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
