Buffer overflow in Google Android
CVE-2020-8860
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Samsung Galaxy S10 Firmware G973FXXS3ASJA, O(8.x), P(9.0), Q(10.0) devices with Exynos chipsets. User interaction is required to exploit this vulnerability in that the target must answer a phone call. The specific flaw exists within the Call Control Setup messages. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the baseband processor. Was ZDI-CAN-9658.
