Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) XML External Entity injection (CVE-ID: CVE-2021-27492)

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

The vulnerability exists due to insufficient validation of user-supplied XML input within the parsing of 3DXML files. A remote attacker can trick a victim to open a specially crafted file or visit a malicious website and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.


2) Out-of-bounds write (CVE-ID: CVE-2021-27488)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error parsing the CATPart files. A remote attacker can create a specially crafted CATPart 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) Stack-based buffer overflow (CVE-ID: CVE-2021-27494)

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

The vulnerability exists due to a boundary error when parsing the STP files. A remote unauthenticated attacker can trick a victim to open a specially crafted file or visit a malicious website, 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.


4) Untrusted Pointer Dereference (CVE-ID: CVE-2021-27496)

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

The vulnerability exists due to untrusted pointer dereference when parsing PRT files. A remote attacker can trick a victim to open a specially crafted file or visit a malicious website and execute arbitrary code on the targeted system.


5) Out-of-bounds write (CVE-ID: CVE-2021-27490)

The vulnerability allows a remote attacker to compromise vulnerable system.

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