Description

This security bulletin contains information about 6 vulnerabilities.


1) Type Confusion (CVE-ID: CVE-2021-31344)

CWE-ID: CWE-843 - Type confusion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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.
