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).
