Description
This security bulletin contains information about 8 vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2020-35683)
CWE-ID: CWE-125 - Out-of-bounds read
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 a boundary condition in the ICMP component. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.
2) Input validation error (CVE-ID: CVE-2020-35684)
CWE-ID: CWE-20 - Improper input validation
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 insufficient validation of user-supplied input in the TCP compponent. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
3) Spoofing attack (CVE-ID: CVE-2020-35685)
CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to TCP ISNs are generated in a predictable manner. A remote attacker can spoof page content.
4) Out-of-bounds read (CVE-ID: CVE-2020-25767)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:L/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 in the DNSv4 component. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.
5) Input validation error (CVE-ID: CVE-2020-25926)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the DNS client does not set sufficiently random transaction IDs in the DNSv4 component. A remote attacker can pass specially crafted input to the application and perform a cache poisoning attack.
6) Out-of-bounds read (CVE-ID: CVE-2020-25927)
CWE-ID: CWE-125 - Out-of-bounds read
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 a boundary condition in the DNSv4 component. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.
7) Out-of-bounds write (CVE-ID: CVE-2020-25928)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input in the DNSv4 component. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.
8) Input validation error (CVE-ID: CVE-2021-31228)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to insufficient validation of user-supplied input in the DNSv4 component. A remote attacker can predict the source port of DNS queries to send forged DNS response packets and perform a cache poisoning attack.
