Summary

An issue was discovered in certain Apple products. iOS before 10.2 is affected. macOS before 10.12.2 is affected. watchOS before 3.1.3 is affected. The issue involves the "CoreFoundation" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted string.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

descriptionThe remote host is running a version of macOS that is 10.12.x prior to 10.12.2. It is, therefore, affected by multiple vulnerabilities in the following components : - apache_mod_php - AppleGraphicsPowerManagement - Assets - Audio - Bluetooth - CoreCapture - CoreFoundation - CoreGraphics - CoreMedia External Displays - CoreMedia Playback - CoreStorage - CoreText - curl - Directory Services - Disk Images - FontParser - Foundation - Grapher - ICU - ImageIO - Intel Graphics Driver - IOFireWireFamily - IOAcceleratorFamily - IOHIDFamily - IOKit - IOSurface - Kernel - kext tools - libarchive - LibreSSL - OpenLDAP - OpenPAM - OpenSSL - Power Management - Security - syslog - WiFi - xar Note that successful exploitation of the most serious issues can result in arbitrary code execution. Furthermore, CVE-2016-6304, CVE-2016-7596, and CVE-2016-7604 also affect Mac OS X versions 10.10.5 and 10.11.6. However, this plugin does not check those versions.
