The vulnerability allows a remote attacker to gain access to sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to improper handling of length parameter inconsistency in Pv4/ICMPv4 component. A remote attacker can send a specially crafted packet and trigger out-of-bounds read, leading to information disclosure or denial of service condition.
4) Input validation error (CVE-ID: CVE-2020-11899)
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 IPv6 component. A remote attacker on the local network can pass specially crafted packet, trigger out-of-bounds read and perform a denial of service (DoS) attack.
5) Double Free (CVE-ID: CVE-2020-11900)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in IPv4 tunneling component. A remote attacker can pass specially crafted packet to the application, trigger double free error and cause a denial of service condition on the target system.
6) Input validation error (CVE-ID: CVE-2020-11901)
The vulnerability allows a remote attacker to execute arbitrary code on the system.
The vulnerability exists due to insufficient validation of user-supplied input in DNS resolver component. A remote attacker can send a specially crafted packet and execute arbitrary code on the target system.
7) Input validation error (CVE-ID: CVE-2020-11902)
The vulnerability allows a remote attacker to gain access to sensitive information or perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in IPv6 over IPv4 tunneling component. A remote attacker can send a specially crafted packet to the application and trigger out-of-bounds read, leading to information disclosure or denial of service condition.
8) Out-of-bounds read (CVE-ID: CVE-2020-11903)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in DHCP component. A remote attacker on the local network can send a specially crafted packet, trigger out-of-bounds read error and read contents of memory on the system.
9) Integer overflow (CVE-ID: CVE-2020-11904)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in memory allocation component. A remote attacker can send a specially crafted packet, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Out-of-bounds read (CVE-ID: CVE-2020-11905)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
