Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2021-38438)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error when processing PDW files. A remote attacker can trick a victim to open a specially crafted project file and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


2) Out-of-bounds write (CVE-ID: CVE-2021-38426)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when parsing project files. A remote attacker can create a specially crafted PDW 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) Unexpected Sign Extension (CVE-ID: CVE-2021-38434)

The vulnerability allows a remote attacker to compromise the target system.

The vulnerability exists due to unexpected sign extension when parsing project files. A remote attacker can trick a victim to open a specially crafted PDW file and execute arbitrary code on the target system.


4) Stack-based buffer overflow (CVE-ID: CVE-2021-38430)

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

The vulnerability exists due to a boundary error when parsing project files. A remote unauthenticated attacker can trick a victim to open a specially crafted PDW file, 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.


5) Buffer overflow (CVE-ID: CVE-2021-38436)

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

The vulnerability exists due to a boundary error when parsing project files. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

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


6) Buffer overflow (CVE-ID: CVE-2021-38442)

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

The vulnerability exists due to a boundary error when parsing project files. A remote attacker can create a specially crafted PDW or PLC file, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

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


7) Out-of-bounds read (CVE-ID: CVE-2021-38440)

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

The vulnerability exists due to a boundary condition when processing PDW files. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
