CVE-2009-1754 Information

Description

The PackageManagerService class in services/java/com/android/server/PackageManagerService.java in Android 1.5 through 1.5 CRB42 does not properly check developer certificates during processing of sharedUserId requests at an application’s installation time which allows remote user-assisted attackers to access application data by creating a package that specifies a shared user ID with an arbitrary application.
