Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 10/10


Stack-based buffer overflow in dsInstallerService.dll in the Juniper Installer Service, as used in Juniper Odyssey Access Client 4.72.11421.0 and other products, allows remote attackers to execute arbitrary code via a long string in a malformed DSSETUPSERVICE_CMD_UNINSTALL command to the NeoterisSetupService named pipe.

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.
