Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 10/10


Stack-based buffer overflow in the DtbClsLogin function in Yosemite Backup 8.7 allows remote attackers to (1) execute arbitrary code on a Linux platform, related to; or (2) cause a denial of service (application crash) and possibly execute arbitrary code on a Windows platform, related to ytwindtb.dll; via a long username field during authentication.

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.
