The parse_string_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (memory allocation error) via a crafted plist file.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libplist: Out-of-bounds heap buffer read in plistutil (CVE-2017-5545)

  - The parse_dict_node function in bplist.c in libplist allows attackers to cause a denial of service (out-     of-bounds heap read and crash) via a crafted file. (CVE-2017-5834)

  - libplist allows attackers to cause a denial of service (large memory allocation and crash) via vectors     involving an offset size of zero. (CVE-2017-5835)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the libplist package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The parse_string_node function in bplist.c in     libimobiledevice libplist 1.12 allows local users to     cause a denial of service (memory allocation error) via     a crafted plist file.(CVE-2017-6436)

  - Heap-based buffer overflow in the parse_string_node     function in bplist.c in libimobiledevice libplist 1.12     allows local users to cause a denial of service     (out-of-bounds write) via a crafted plist     file.(CVE-2017-6439)

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

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.
