SB2025011484 - Multiple vulnerabilities in Adobe Substance 3D Stager

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2025-21128)

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

The vulnerability exists due to a boundary error when handling files. A remote attacker can trick the victim into opening a specially crafted file, trigger a 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) Heap-based buffer overflow (CVE-ID: CVE-2025-21129)

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

The vulnerability exists due to a boundary error when handling files. A remote attacker can trick the victim into opening a specially crafted file, trigger a 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.

3) Out-of-bounds write (CVE-ID: CVE-2025-21130)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.

4) Out-of-bounds write (CVE-ID: CVE-2025-21131)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.

5) Out-of-bounds write (CVE-ID: CVE-2025-21132)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can create a specially crafted file, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.
