CVE-2021-34318 : Security Advisory and Response

A vulnerability has been identified in JT2Go and Teamcenter Visualization software versions prior to V13.2. The vulnerability lies in the BMP_loader.dll library, where user-supplied data is not properly validated when parsing PCT files, leading to a potential out-of-bounds write issue. This flaw could allow an attacker to execute malicious code within the context of the affected process.

Understanding CVE-2021-34318

This section delves into the details of the identified vulnerability and its implications.

What is CVE-2021-34318?

The vulnerability in JT2Go and Teamcenter Visualization software versions prior to V13.2 stems from inadequate validation of user-supplied data during the parsing of PCT files by the BMP_loader.dll library. This oversight could enable an attacker to execute arbitrary code within the affected application's context.

The Impact of CVE-2021-34318

Exploitation of this vulnerability could result in an out-of-bounds write past the end of an allocated structure, potentially leading to a compromise of the affected system and unauthorized code execution.
