More information:

libplist is a library for reading and writing the Apple binary and XML property lists format. It's part of the libimobiledevice stack, providing access to iDevices (iPod, iPhone, iPad ...).

  • CVE-2017-5209

    The base64decode function in base64.c 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.

  • CVE-2017-5545

    The main function in plistutil.c allows 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-2017-5834

    The parse_dict_node function in bplist.c allows attackers to cause a denial of service (out-of-bounds heap read and crash) via a crafted file.

  • CVE-2017-5835

    libplist allows attackers to cause a denial of service (large memory allocation and crash) via vectors involving an offset size of zero.

  • CVE-2017-6435

    The parse_string_node function in bplist.c allows local users to cause a denial of service (memory corruption) via a crafted plist file.

  • CVE-2017-6436

    The parse_string_node function in bplist.c allows local users to cause a denial of service (memory allocation error) via a crafted plist file.

  • CVE-2017-6439

    Heap-based buffer overflow in the parse_string_node function in bplist.c allows local users to cause a denial of service (out-of-bounds write) via a crafted plist file.

  • CVE-2017-7982

    Integer overflow in the plist_from_bin function in bplist.c allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted plist file.

For Debian 8 Jessie, these problems have been fixed in version 1.11-3+deb8u1.

We recommend that you upgrade your libplist packages.
