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.
-
Verify Android versionCheck Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Device is running Android 9.0 (Pie)
-
Confirm Samsung Gallery app presenceCheck if Samsung Gallery app (package: com.sec.android.gallery3d) is installed in Settings > Apps, or run 'pm list packages | grep gallery3d' via ADBAffected if Samsung Gallery is installed on the device
-
Check security patch levelCheck Settings > About Phone > Security patch level, or run 'getprop ro.build.version.security_patch' via ADBAffected if Security patch level is earlier than January 2020 (before 2020-01)
-
Inspect Gallery cached data accessibilityUse ADB to list files in /data/data/com.sec.android.gallery3d/cache/ and check if other apps can read them via 'ls -la /data/data/com.sec.android.gallery3d/cache/'Affected if Cached files exist and are accessible without proper restrictions
Device is affected if it runs Android 9.0 with Samsung Gallery installed and has a security patch level before the January 2020 update, as cached data may be improperly accessible.

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 dataApply the Samsung security updates released in January 2020 (SVE-2019-16010, SVE-2019-16011, SVE-2019-16012) which contain the fix for the Gallery cached data leakage issue.
