Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-5595)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the TCP/IP function. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Session Fixation (CVE-ID: CVE-2020-5596)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the session invalidation issue in the TCP/IP function. A remote attacker can use a specially crafted packet and cause a denial of service condition on the target system.
3) NULL pointer dereference (CVE-ID: CVE-2020-5597)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the TCP/IP function. A remote attacker can trigger denial of service conditions via a specially crafted packet.
4) Improper access control (CVE-ID: CVE-2020-5598)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in the TCP/IP function. A remote attacker can use a specially crafted packet, bypass implemented security restrictions and gain unauthorized access to the application.
5) Improper Neutralization of Argument Delimiters in a Command (CVE-ID: CVE-2020-5599)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exixts due to improper neutralization of argument delimiters in a command within the TCP/IP function. A remote attacker on the local network can use a specially crafted packet and cause a denial of service condition on the target system.
6) Resource management error (CVE-ID: CVE-2020-5600)
The vulnerability allows a remote attacker to gain access to sensitive information on the system
The vulnerability exists due to improper management of internal resources with the application in the TCP/IP function. A remote attacker can pass specially crafted data to the application and obtain sensitive information on the target system.
