"This update for libplist fixes the following issues :

  - CVE-2017-5209: The base64decode function in libplist

    over-read) via split encoded Apple Property List data
    (bsc#1019531).

  - 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-2017-5836: 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-2017-6440: Ensure that sanity checks work on 32-bit
    platforms. (bsc#1029631)

  - CVE-2017-7982: Add some safety checks, backported from
    upstream (bsc#1035312).

  - CVE-2017-5836: A maliciously crafted file could cause
    the application to crash. (bsc#1023807).

  - CVE-2017-5835: Malicious crafted file could cause
    libplist to allocate large amounts of memory and consume
    lots of CPU (bsc#1023822)

  - CVE-2017-5834: Maliciou crafted file could cause a heap
    buffer overflow or segmentation fault (bsc#1023848)
