CVE-2015-5829

Vulnerability

The vulnerability exists in the Data Detectors Engine of Apple iOS versions prior to 9. The engine parses text files to detect structured data (phone numbers, addresses, etc.). When handling a specially crafted text file, a memory corruption issue occurs, leading to arbitrary code execution or denial of service [1].

Exploitation

An attacker can exploit this remotely by delivering a malicious text file to a target device. The text file must be opened or processed by the Data Detectors Engine, which can happen automatically in applications like Messages, Mail, or Safari when the file is displayed or scanned. No special authentication or local access is required [1].

Impact

Successful exploitation allows an attacker to execute arbitrary code on the device or cause a denial of service (memory corruption). This could result in complete compromise of the device, including access to user data and system functions. The vulnerability affects iPhones, iPads, and iPod touches running iOS prior to version 9 [1].

Mitigation

The vulnerability is fixed in iOS 9, released on September 16, 2015. Users should update to iOS 9 or later. Apple does not provide workarounds for unpatched versions. No CVE-specific workaround is documented; updating is the sole mitigation [1].
