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
The com.glitter.caller.screen (aka iCaller, Caller Theme & Dialer) application through 1.1 for Android enables any application (with no permissions) to place phone calls without user interaction by sending a crafted intent via the com.glitter.caller.screen.DialerActivity component.

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

The iCaller Android application through version 1.1 exposes the com.glitter.caller.screen.DialerActivity component without proper access controls, allowing any installed application to send crafted intents that trigger outgoing phone calls without user interaction or elevated permissions.

MitigationDisable or properly protect the DialerActivity component by setting android:exported='false' or adding android:permission checks; implement user confirmation dialogs before placing any calls originated from intents.

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. Confirm iCaller app is installed
    Run 'adb shell pm list packages | grep icaller' or 'adb shell pm list packages | grep glitter' to check if the iCaller app exists on the device
    Affected if The package name containing 'icaller' or 'glitter.caller.screen' is found in the installed packages
  2. Identify the installed version
    Run 'adb shell dumpsys package <package_name>' and look for versionName/versionCode, or use 'adb shell pm dump <package_name> | grep -i version'
    Affected if The installed version is 1.1 or any version lower than 1.1 (the fixed version is not specified)
  3. Extract and inspect the AndroidManifest.xml
    Obtain the APK (via 'adb pull /data/app/<package>/base.apk') and run 'aapt dump badging <apk> | grep -i activity' to list exported components, or use an APK analysis tool to decompile and inspect AndroidManifest.xml directly
    Affected if The com.glitter.caller.screen.DialerActivity component is present and shows android:exported='true' or has no android:exported attribute set (defaults to true)
  4. Verify component access controls
    In the decompiled AndroidManifest.xml, check the <activity> tag for DialerActivity: look for android:exported='false' or android:permission attribute with a custom permission
    Affected if The DialerActivity has no android:permission attribute AND android:exported is not set to false, meaning any app can send intents to trigger calls

You are affected if the iCaller Android app version 1.1 or lower is installed AND the DialerActivity component is exported without permission protection, allowing other apps to trigger outgoing calls without user interaction.
