CVE-2014-7917
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 · uneditedInteger overflow in SampleTable.cpp in libstagefright in Android before 5.0.0 has unspecified impact and attack vectors, aka internal bug 15342615.
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 · moderate confidenceInteger overflow vulnerability in libstagefright's SampleTable.cpp component affecting Android devices prior to 5.0.0. The overflow occurs during media sample table parsing and could allow remote code execution via specially crafted media files.

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 OS versionNavigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Version is 4.4.4 or lower (4.4, 4.3, 4.2, etc.)
-
Confirm libstagefright library is presentVerify /system/lib/libstagefright.so exists using 'adb shell ls -la /system/lib/libstagefright.so'Affected if Library exists on Android 4.4.4 or lower
-
Verify media server is runningCheck if mediaserver process is active: 'adb shell ps -A | grep mediaserver'Affected if Media server is processing on an affected Android version
Device is affected if running Android 4.4.4 or lower and the libstagefright component is present and active for media file parsing.

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.
dbcve · scopedApply Android security patches (CTS-compatible) to affected devices or upgrade to Android 5.0+; implement network-level media file filtering as temporary workaround.
Android 5.0.0 (Lollipop) or later
- 1. Identify all Android devices running version 4.4.4 or earlier in the organization
- 2. Check each device's manufacturer and carrier update support for Android 5.0.0 (Lollipop)
- 3. Back up critical data on devices scheduled for update
- 4. Apply OTA (Over-the-Air) update or flash factory image to Android 5.0.0 or later
- 5. Verify successful update by checking Android version in Settings > About Phone > Android version
