Description
This security bulletin contains information about 6 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-2021-31885)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition. A remote attacker can send specially crafted TFTP commands, trigger out-of-bounds read error and read contents of memory on the system.
5) 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.
6) 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.
