CVE-2019-2082
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn libxaac there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution with no additional execution privileges needed. User interaction is needed for exploitation. Product: AndroidVersions: Android-10Android ID: A-117495103
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA buffer overflow vulnerability exists in libxaac (Android's AAC audio decoder library) where a missing bounds check allows an out-of-bounds write. This occurs when processing a specially crafted AAC audio file, leading to potential remote code execution. User interaction (opening a malicious audio file) is required for exploitation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Version is exactly 10.0 (Android 10)
-
Verify libxaac library presenceCheck for /system/lib64/libaudiooaac.so or /system/lib/libaudiooaac.so using a file manager or 'find /system -name *xaac*' via ADB shellAffected if The libxaac library exists on the device (it is present in Android 10.0) and is used by audio playback components
-
Identify apps handling AAC audioReview installed apps that process audio files, particularly third-party media players, ringtone setters, or voice recording appsAffected if Applications that open AAC audio files from external or untrusted sources are installed and regularly used
-
Check for user exposure to untrusted audio filesDetermine whether the device user typically opens AAC audio files received via messaging apps, email attachments, or downloaded from the internetAffected if Users open audio files from untrusted or unknown sources without verification
The device is affected if it runs Android 10.0 and has the vulnerable libxaac library present, with users who may open crafted AAC audio files from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Android to a version that includes the patched libxaac library, as the vulnerability is in the native audio decoder and cannot be mitigated through configuration changes. Users should avoid opening audio files from untrusted sources until the device receives the security update.
