The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in the Link Layer Discovery Protocol (LLDP) functionality. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2022-20687)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in the Link Layer Discovery Protocol (LLDP) functionality. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Input validation error (CVE-ID: CVE-2022-20688)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to missing length validation of certain Cisco Discovery Protocol packet header fields. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Out-of-bounds read (CVE-ID: CVE-2022-20689)
The vulnerability allows a remote attacker to compromise the target system.

6) Input validation error (CVE-ID: CVE-2022-20691)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to missing length validation of certain Cisco Discovery Protocol packet header fields. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
7) Out-of-bounds read (CVE-ID: CVE-2022-20766)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the Cisco Discovery Protocol functionality. A remote attacker can trigger out-of-bounds read error and cause a denial of service condition on the system.
