CVE-2020-0204

In InstallPackage of package.cpp, there is a possible bypass of a signature check due to a Time of Check/Time of Use condition. This could lead to local escalation of privilege by allowing a bypass of the initial zip file signature check for an OS update with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-10Android ID: A-136498130
