Summary

An issue was discovered in certain Apple products. iOS before 10.1 is affected. Safari before 10.0.1 is affected. iCloud before 6.0.1 is affected. iTunes before 12.5.2 is affected. tvOS before 10.0.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

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.

    descriptionAccording to its banner, the version of Apple TV on the remote device is prior to 10.0.1. It is, therefore, affected by multiple vulnerabilities : - A flaw exists in WebKit when handling the location attribute that allows an unauthenticated, remote attacker to bypass the cross-origin policies and disclose sensitive user information. (CVE-2016-4613) - An out-of-bounds read error exists in the FontParser component when handling specially crafted font files that allows an unauthenticated, remote attacker to disclose sensitive information. (CVE-2016-4660) - An unspecified flaw exists in the Sandbox Profiles component that allows a local attacker, via a specially crafted application, to disclose the metadata of photo directories. (CVE-2016-4664) - An unspecified flaw exists in the Sandbox Profiles component that allows a local attacker, via a specially crafted application, to disclose the metadata of audio recordings. (CVE-2016-4665) - Multiple memory corruption issues exist in Webkit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these to execute arbitrary code. (CVE-2016-4666, CVE-2016-4677, CVE-2016-7578) - Multiple unspecified flaws exist in the System Boot component, within MIG generated code, due to improper validation of input. A local attacker can exploit these to terminate the system or execute arbitrary code with elevated privileges. (CVE-2016-4669) - A memory corruption issue exists in the CoreGraphics component when handling specially crafted JPEG files. An unauthenticated, remote attacker can exploit this, via a specially crafted file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4673) - An unspecified logic issue exists in libxpc that allows a local attacker to execute arbitrary code with root privileges. (CVE-2016-4675) - A flaw exists in libarchive due to improper path validation when creating temporary files during archive extraction. An unauthenticated, remote attacker can exploit this, via a symlink attack, to overwrite arbitrary files. (CVE-2016-4679) - An unspecified flaw exists in the Kernel component due to improper sanitization of input. A local attacker can exploit this to disclose kernel memory contents. (CVE-2016-4680) - An overflow condition exists in the FontParser component due to improper validation when parsing font files. An unauthenticated, remote attacker can exploit this to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-4688) - A flaw exists in the CFNetwork Proxies component when handling proxy credentials that allows a man-in-the-middle attacker to disclose sensitive user information. (CVE-2016-7579) - A flaw exists in the AppleMobileFileIntegrity component due to improper validation of code signatures. A local attacker can exploit this to have a signed executable substitute code with the same team ID. (CVE-2016-7584) - Multiple race conditions exist in various IOKit drivers related to how they use task struct pointers. A local attacker can exploit this to execute arbitrary code with kernel-level privileges. (CVE-2016-7613) Note that only 4th generation models are affected by these vulnerabilities.

    descriptionA large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory.
