(Pwn2own) Samsung Galaxy S8 Shannon GPRS Stack-based Buffer Overflow Remote Code Execution Vulnerability
September 21st, 2018
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S8. User interaction is required to exploit this vulnerability in that the target must have their cellular radios enabled.
The specific flaw exists within the handling of IPCP headers. 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 under the context of the baseband processor.
