Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2020-25066)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Treck HTTP Server component. A remote attacker can pass specially crafted request to the server, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Out-of-bounds write (CVE-ID: CVE-2020-27337)

The vulnerability allows a remote attacker to perform a DoS attack or compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within Treck IPv6 component. A remote attacker can send specially crafted packets to the system, trigger out-of-bounds write and crash the system or potentially execute arbitrary code.


3) Out-of-bounds read (CVE-ID: CVE-2020-27338)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition within the DHCPv6 client component in Treck TCP/IP. A remote attacker can send specially crafted packets to the system, trigger an out-of-bounds read and perform a denial of service (DoS) attack.


4) Out-of-bounds read (CVE-ID: CVE-2020-27336)

The vulnerability allows a remote attacker to perform a denial of service attack..

The vulnerability exists due to a boundary condition within the IPv6 component in Treck TCP/IP. A remote attacker can send specially crafted packets to the system, trigger out-of-bounds read error and perform a denial of service (DoS) attack.
