Summary

Heap-based buffer overflow in the DNS client library in configd in Apple iOS before 9.1, OS X before 10.11.1, and watchOS before 2.0.1 allows attackers to execute arbitrary code via a crafted app that sends a spoofed configd response to a client.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
