Summary

WebKit in Apple iOS before 10, tvOS before 10, iTunes before 12.5.1 on Windows, and Safari before 10 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, a different vulnerability than CVE-2016-4759, CVE-2016-4765, CVE-2016-4767, and CVE-2016-4768.

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.

    NASL idITUNES_12_5_1_BANNER.NASL
    descriptionThe version of Apple iTunes running on the remote Windows host is prior to 12.5.1. It is, therefore, affected by multiple vulnerabilities : - A remote code execution vulnerability exists due to improper handling of error prototypes. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a maliciously crafted website, to execute arbitrary code. (CVE-2016-4728) - An information disclosure vulnerability exists in WebKit due to a permission issue caused by improper handling of the location variable. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a maliciously crafted website, to disclose sensitive information. (CVE-2016-4758) - Multiple memory corruption errors exist in WebKit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these issues, by convincing a user to visit a maliciously crafted website, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4759, CVE-2016-4762, CVE-2016-4764, CVE-2016-4765, CVE-2016-4766, CVE-2016-4767, CVE-2016-4768, CVE-2016-4769) - A rebinding flaw exists in WebKit due to a failure to restrict HTTP/0.9 responses to default ports and cancel resource loads if a document is loaded with a different HTTP protocol version. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a maliciously crafted website, to access non-HTTP services. (CVE-2016-4760) - A security bypass vulnerability exists in WebKit in the WKWebView component due to a failure to properly verify X.509 certificates from HTTPS servers. A man-in-the-middle attacker can exploit this, via a specially crafted certificate, to spoof servers and disclose or manipulate network traffic. (CVE-2016-4763) Note that Nessus has not tested for these issues but has instead relied only on the application
