Coming to the latest Android security patch, several security vulnerabilities have been addressed, as detailed in the Android Security Bulletin for November 2020. The official post states that Android partners are notified of all security vulnerabilities affecting Android devices at least a month before publication. The list of vulnerabilities have been broadly categorised into Android runtime, Framework, Media Framework, System, and Google Play system updates.
The ‘Android runtime' vulnerability could “enable a local malicious application to bypass user interaction requirements in order to gain access to additional permissions.” The ‘Framework' vulnerability could, in the most severe case, “enable a remote attacker using a specially crafted message to cause a permanent denial of service.” A ‘Media framework' vulnerability could enable “remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process.” In case of a severe ‘System' vulnerability, it could “enable a proximal attacker using a specially crafted transmission to execute arbitrary code within the context of a privileged process,” Google states.
Google will be rolling out the updates in phases depending on carrier and device.
