CVE-2017-0406 Google CVE debrief

Who should care

Android fleet operators, mobile security teams, and device owners running affected Android builds should care, especially where untrusted media files may be opened or processed on 6.0, 6.0.1, 7.0, 7.1.0, or 7.1.1 devices.

Technical summary

The vulnerability affects the libhevc library used by Android Mediaserver during media file and data processing. NVD identifies CWE-119 and a CVSS 3.0 vector of AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating that successful exploitation can have full confidentiality, integrity, and availability impact within the Mediaserver process context. The CVE description says a specially crafted file could trigger memory corruption during parsing.

Defensive priority

High. This affects media parsing in a privileged Android process and can lead to code execution or device compromise impact within Mediaserver. Prioritize patching and update compliance on any exposed Android 6.x and 7.x devices.

Recommended defensive actions

• Apply the Android security update that addresses CVE-2017-0406, or a later cumulative update, on all affected devices.
• Inventory managed Android devices for vulnerable versions referenced by NVD and the CVE description, including Android 6.0, 6.0.1, 7.0, 7.1.0, and 7.1.1.
• Restrict or closely control handling of untrusted media files on affected devices until updates are confirmed.
• Use MDM or compliance tooling to enforce minimum patch levels and remove unsupported Android builds from managed fleets.
• Treat unexpected crashes or anomalies in Mediaserver or libhevc as security-relevant and investigate them promptly.
