Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Samsung Galaxy S8 G950FXXU1AQL5. 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. Was ZDI-CAN-5368.

• CWE-121Stack-based Buffer OverflowA stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
