Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Improper input validation (CVE-ID: CVE-2018-7185)
The vulnerability allows a remote authenticated attacker to cause DoS condition on the target system.The weakness exists due to insufficient validation of user-supplied input. A remote attacker can submit continuous crafted packets and cause the service to crash.
2) Denial of service (CVE-ID: CVE-2018-7184)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to insufficient security restrictions. A remote attacker can cause interleaved symmetric mode to crash.
3) Memory corruption (CVE-ID: CVE-2018-7183)
The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.The weakness exists in the decodearr() function of the ntpq monitoring and control program for ntpd used by the Network Time Protocol due to boundary error while attempting to decode an array in a response string when formatted data is being displayed. A remote attacker who is able to read an ntpq request while the request is being transmitted to a remote ntpd server can forge and send a specially crafted response to the targeted system prior to the remote ntpd server sending its response, trigger out-of-bounds write in the decodearr() function and inject and execute arbitrary code.
4) Information disclosure (CVE-ID: CVE-2018-7182)
The vulnerability allows a remote unautheticated attacker to obtain potentially sensitive information.
The weakness exists due to insufficient validation user-supplied input. A remote attacker can submit a specially crafted mode 6 packet and gain access to potentially sensitive information.
