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 · unedited
Multiple integer underflows in the ESDS::parseESDescriptor function in ESDS.cpp in libstagefright in Android before 5.1.1 LMY48I allow remote attackers to execute arbitrary code via crafted ESDS atoms, aka internal bug 20139950, a related issue to CVE-2015-4493.

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 confidence

Integer underflow vulnerabilities in the ESDS::parseESDescriptor function within libstagefright's ESDS.cpp allow remote attackers to execute arbitrary code via specially crafted ESDS atoms in media files. This affects Android devices before version 5.1.1 (LMY48I).

MitigationApply Android system update LMY48I or later to patched devices; avoid processing untrusted media files until update is applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Android OS version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is 5.1 or earlier (5.1.1 LMY48I and later are patched)
  2. Verify libstagefright is present
    Check for /system/lib/libstagefright.so on the device, or look for stagefright-related libraries in the system partition
    Affected if The library exists (it is present in all Android versions up to 5.1) and the OS version is vulnerable
  3. Identify media processing apps
    Review installed apps that handle audio/video files - typical candidates include browsers, messaging apps, media players, and file managers
    Affected if Any app that parses MPEG-4 or 3GP media files is a potential attack vector for this vulnerability

Your device is affected if it runs Android 5.1 or earlier and contains the libstagefright library, since the vulnerability lies in how this library parses ESDS atoms within media files.

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.

Upgrade available Upgrade to a release after 5.1
Interim mitigation

Apply Android system update LMY48I or later to patched devices; avoid processing untrusted media files until update is applied.

Recommended fix High confidence

Android 5.1.1 LMY48I or later

  1. Update your Android device to version 5.1.1 (LMY48I) or later to patch the integer underflow vulnerability in libstagefright
  2. Verify the Android version by navigating to Settings > About Phone > Android version
  3. If your device cannot be updated to 5.1.1 or later, contact your device manufacturer for available security patches
Caveat Android version upgrades may cause compatibility issues with older applications; ensure critical apps are compatible before upgrading
