The base64encode function in base64.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (out-of-bounds read) 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.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

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

  - 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.(CVE-2017-5209)

  - The base64encode function in base64.c in     libimobiledevice libplist 1.12 allows local users to     cause a denial of service (out-of-bounds read) via a     crafted plist file.(CVE-2017-6437)

  - The parse_data_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-2017-6440)
