CVE-2017-18672
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), M(6.0), and N(7.x) software. Because of incorrect exception handling for Intents, a local attacker can force a reboot within framework.jar. The Samsung ID is SVE-2017-8390 (May 2017).
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 confidenceThis vulnerability exists in Samsung's Android framework (framework.jar) on devices running L (5.0/5.1), M (6.0), and N (7.x) software versions. The issue involves incorrect exception handling for Intents, which allows a local attacker to craft malicious Intents that trigger an unhandled exception resulting in device reboot.

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.
-
Determine Android versionGo to Settings > About Phone > Android version (or run 'getprop ro.build.version.release' via ADB shell)Affected if Version is 5.0, 5.1, 6.0, 7.0, 7.1.0, 7.1.1, or 7.1.2
-
Confirm device manufacturerGo to Settings > About Phone > Manufacturer (or run 'getprop ro.product.manufacturer' via ADB shell)Affected if Manufacturer is Samsung (the vulnerability exists in Samsung's Android framework)
-
Check security patch levelGo to Settings > About Phone > Security patch level (or run 'getprop ro.build.version.security_patch' via ADB shell)Affected if Patch level is earlier than the SVE-2017-8390 fix date, or patch level is not displayed/empty indicating no updates applied
-
Verify Intent broadcast receiving appsReview installed applications in Settings > Apps > Menu > Show system apps; check for any untrusted or suspicious apps with RECEIVE_BOOT_COMPLETED or broad Intent broadcast permissionsAffected if Malicious app with elevated Intent privileges is installed and able to send crafted Intents to framework components
Device is affected if it is a Samsung device running Android 5.0-7.1.2 and the SVE-2017-8390 security patch has not been applied.

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 dataUsers should apply the Samsung security update (SVE-2017-8390) which patches the framework.jar to properly handle Intent exceptions. Enterprise mobility managers should ensure affected Samsung devices are enrolled in patch management programs.
