CVE-2017-0466

Vulnerability

A remote code execution vulnerability exists in Android's Mediaserver component due to memory corruption during the processing of specially crafted media files. The issue affects Android versions 6.0, 6.0.1, 7.0, and 7.1.1. The vulnerability is triggered when Mediaserver parses a malicious media file, leading to memory corruption that can be exploited for code execution [1].

Exploitation

An attacker can exploit this vulnerability by delivering a specially crafted media file to the target device, for example via a malicious website, email attachment, or MMS. The user must open the file with an application that uses Mediaserver (e.g., the default media player). No authentication or special network position is required; the attack can be performed remotely [1].

Impact

Successful exploitation results in remote code execution within the context of the Mediaserver process. This can allow the attacker to execute arbitrary code with the privileges of Mediaserver, potentially leading to full compromise of the device's media capabilities and access to sensitive data [1].

Mitigation

Google released a fix for this vulnerability in the March 2017 Android Security Bulletin. Users should ensure their devices have received the security patch level of 2017-03-01 or later. No workaround is available; updating to the patched version is the only mitigation [1].
