Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2017-6736)
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.The weakness exists in the Simple Network Management Protocol (SNMP) subsystem due to buffer overflow when handling malicious input. A remote attacker can send specially crafted SNMP packet via IPv4 or IPv6, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability results in system compromise.
2) Buffer overflow (CVE-ID: CVE-2017-6737)
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.The weakness exists in the Simple Network Management Protocol (SNMP) subsystem due to buffer overflow when handling malicious input. A remote attacker can send specially crafted SNMP packet via IPv4 or IPv6, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability results in system compromise.
3) Buffer overflow (CVE-ID: CVE-2017-6738)
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.The weakness exists in the Simple Network Management Protocol (SNMP) subsystem due to buffer overflow when handling malicious input. A remote attacker can send specially crafted SNMP packet via IPv4 or IPv6, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability results in system compromise.
4) Buffer overflow (CVE-ID: CVE-2017-6739)
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.The weakness exists in the Simple Network Management Protocol (SNMP) subsystem due to buffer overflow when handling malicious input. A remote attacker can send specially crafted SNMP packet via IPv4 or IPv6, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability results in system compromise.
5) Buffer overflow (CVE-ID: CVE-2017-6740)
The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.The weakness exists in the Simple Network Management Protocol (SNMP) subsystem due to buffer overflow when handling malicious input. A remote attacker can send specially crafted SNMP packet via IPv4 or IPv6, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of the vulnerability results in system compromise.
