Description

This security bulletin contains information about 3 secuirty vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2021-38402)

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

The vulnerability exists due to a boundary error when parsing specific project files. 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-2021-38406)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when parsing specific project files. A remote attacker can trigger out-of-bounds write and execute arbitrary code on the target system.

3) Heap-based buffer overflow (CVE-ID: CVE-2021-38404)

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

The vulnerability exists due to a boundary error when parsing specific project files. A remote attacker can pass specially crafted data to the application, 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.
