Description

This security bulletin contains information about 6 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2021-38413)

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

The vulnerability exists due to a boundary error within the parsing of V8 and X1 files in the V-Simulator module. A remote unauthenticated attacker can trigger stack-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-2021-38419)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error within the parsing of V9 files in the V-Simulator module. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.


3) Untrusted Pointer Dereference (CVE-ID: CVE-2021-38401)

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

The vulnerability exists due to untrusted pointer dereference error. A remote attacker can trigger pointer dereference and execute arbitrary code on the target system.


4) Out-of-bounds read (CVE-ID: CVE-2021-38421)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the parsing of V8 files within the V-Simulator module. 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) Access of Uninitialized Pointer (CVE-ID: CVE-2021-38409)

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

The vulnerability exists due to an access of uninitialized pointer. A remote attacker can execute arbitrary code on the target system.


6) Heap-based buffer overflow (CVE-ID: CVE-2021-38415)

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

The vulnerability exists due to a boundary error within the parsing of V8 files within the V-Simulator module. A remote attacker can 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.
