Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2016-1669

High
8.8/10

Summary

The Zone::New function in zone.cc in Google V8 before 5.0.71.47, as used in Google Chrome before 50.0.2661.102, does not properly determine when to expand certain memory allocations, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via crafted JavaScript code.

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.
