Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Type Confusion (CVE-ID: CVE-2021-31344)
The vulnerability allows a remote attacker to compromise the system.
The vulnerability exists due to a type confusion error within ICMP echo packets with fake IP options. A remote attacker can send specially crafted ICMP echo reply messages to arbitrary hosts on the network.
2) Input validation error (CVE-ID: CVE-2021-31345)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the total length of an UDP payload (set in the IP header) is unchecked. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack or gain access to sensitive information on the system.
3) Input validation error (CVE-ID: CVE-2021-31346)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the total length of an UDP payload (set in the IP header) is unchecked. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack or gain access to sensitive information on the system.
4) Out-of-bounds read (CVE-ID: CVE-2021-31881)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker on the local network can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system or cause a denial of service (DoS) condition.
5) Buffer overflow (CVE-ID: CVE-2021-31882)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the DHCP client application when processing DHCP ACK packets. A remote attacker on the local network can trigger memory corruption and cause a denial of service condition on the target system.
6) Buffer overflow (CVE-ID: CVE-2021-31883)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the DHCP client application when processing a DHCP ACK message. A remote attacker on the local network can trigger memory corruption and cause a denial of service condition on the target system or gain access to sensitive information.
7) Improper Null Termination (CVE-ID: CVE-2021-31884)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to the DHCP client application assumes the data supplied with the “hostname” DHCP option NULL is terminated. A remote attacker on the local network can execute arbitrary code on the target system.
8) Integer overflow (CVE-ID: CVE-2021-31889)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow. A remote attacker can send a specially crafted TCP packet, trigger integer overflow and cause a denial of service condition on the target system.
9) Input validation error (CVE-ID: CVE-2021-31890)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the total length of a TCP payload (set in the IP header) is unchecked. A remote attacker can cause a denial of service condition on the target system.
