CVE-2014-4485

Vulnerability

A buffer overflow vulnerability exists in the XML parser of Foundation in Apple iOS before 8.1.3, Apple OS X before 10.10.2, and Apple TV before 7.0.3. The issue is triggered when the parser processes a specially crafted XML document, leading to a buffer overflow that can result in arbitrary code execution or a denial of service (application crash).

Exploitation

An attacker can exploit this vulnerability by persuading a user to open a malicious XML document, either via a web page, email attachment, or other means. No additional authentication or special network position is required beyond delivering the crafted XML content to the target device. The vulnerable code path is reachable through any application that uses the Foundation XML parser on the affected systems.

Impact

Successful exploitation allows the attacker to execute arbitrary code with the privileges of the affected application, potentially gaining full control of the device. Alternatively, an attacker could cause the application to crash, resulting in a denial of service. The scope of compromise includes information disclosure, data corruption, and complete system takeover on the affected platforms.

Mitigation

Apple has addressed this vulnerability in iOS 8.1.3, OS X Yosemite v10.10.2 (and Security Update 2015-001), and Apple TV 7.0.3. Users should update to the latest available versions as listed in the referenced security advisories [1][2][3]. No workarounds have been disclosed, and there is no evidence that this CVE is listed on the CISA KEV.
