CVE-2016-11052
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 · uneditedAn issue was discovered on Samsung mobile devices with L(5.0/5.1) software. je_free in libQjpeg.so in Qjpeg in Qt 5.5 allows memory corruption via a malformed JPEG file. The Samsung ID is SVE-2015-5110 (January 2016).
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 confidenceMemory corruption vulnerability in the je_free function within libQjpeg.so (Qjpeg component of Qt 5.5) on Samsung mobile devices running Android L (5.0/5.1). The flaw is triggered by processing a malformed JPEG file, leading to heap corruption via improper memory handling during file parsing.

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.
-
Confirm device manufacturer and modelCheck the device settings under Settings > About Phone > Manufacturer and Model to verify it is a Samsung device.Affected if The device is not a Samsung mobile device (this vulnerability only affects Samsung devices).
-
Verify Android OS versionGo to Settings > About Phone > Android version to determine the installed OS version.Affected if The device is running Android 5.0 or 5.1 (Android L).
-
Check for the vulnerable libraryUsing a file manager or ADB shell, locate the file /system/lib/libQjpeg.so on the device filesystem.Affected if The file libQjpeg.so exists on the device (indicating the Qt Qjpeg component is present).
-
Confirm Qt 5.5 is in useIf libQjpeg.so exists, check the file properties or version metadata to identify the Qt version it belongs to.Affected if The library belongs to Qt version 5.5 (the specific version containing the vulnerable je_free function).
The device is affected if it is a Samsung mobile device running Android 5.0 or 5.1 that contains the Qt 5.5 Qjpeg component (libQjpeg.so) with the vulnerable je_free function.

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 dataSamsung addressed this in their January 2016 security update (SVE-2015-5110). Users should apply available system updates. Avoid opening untrusted JPEG files from unknown sources until the device is patched.
