LGInstallService - Deletion of arbitrary files with system privilege

he vulnerability is to delete arbitrary files in LGInstallService ("com.lge.lginstallservies") app. The app contains the exported "com.lge.lginstallservies.InstallService" service that exposes an AIDL interface. All its "installPackage*" methods are finally calling the "installPackageVerify()" method that performs signature validation after the delete file method. An attacker can control conditions so this security check is never performed and an attacker-controlled file is deleted.
