Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Memory leak (CVE-ID: CVE-2018-0158)
The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.The weakness exists in the Internet Key Exchange Version 2 (IKEv2) module due to incorrect processing of certain IKEv2 packets. A remote attacker can send specially crafted IKEv2 packets, trigger memory leak and cause the service to crash.
2) Buffer overflow (CVE-ID: CVE-2018-0151)
The vulnerability allows a remote unauthenticated attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to boundary error in packets that are destined for UDP port 18999. A remote attacker can send specially crafted packets, trigger buffer overflow, cause the service to crash and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
3) Buffer overflow (CVE-ID: CVE-2018-0167)
The vulnerability allows an adjacent unauthenticated attacker to cause DoS condition or execute arbitrary code with elevated privileges on the target system.
The weakness exists in the LLDP subsystem due to improper error handling of malformed LLDP messages. An adjacent attacker can submit a specially crafted LLDP protocol data unit (PDU), trigger buffer overflow, cause the service to crash or execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
4) Memory corruption (CVE-ID: CVE-2018-0175)
The vulnerability allows an adjacent unauthenticated attacker to cause DoS condition or execute arbitrary code with elevated privileges on the target system.
The weakness exists in the LLDP subsystem due to improper handling of certain fields in an LLDP message. An adjacent attacker can submit a specially crafted LLDP PDU, trick the victim into executing a specific show command in the CLI, trigger memory corruption, cause the service to crash or execute arbitrary code with root privileges.
Successful exploitation of the vulnerability may result in system compromise.
