Description

A heap corruption vulnerability exists in the Advantech TP-3250 printer driver's DrvUI_x64_ADVANTECH.dll (v0.3.9200.20789) when DocumentPropertiesW() is called with a valid dmDriverExtra value but an undersized output buffer. The driver incorrectly assumes the output buffer size matches the input buffer size, leading to invalid memory operations and heap corruption. This vulnerability can cause denial of service through application crashes and potentially lead to code execution in user space. Local access is required to exploit this vulnerability.

CWE ID	Description
CWE-122	A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

Attack-Flow Graph

Executive Summary

This vulnerability is a heap corruption issue in the Advantech TP-3250 printer driver, specifically in the DrvUI_x64_ADVANTECH.dll file. It occurs when the DocumentPropertiesW() function is called with a valid dmDriverExtra value but an output buffer that is smaller than expected. The driver mistakenly assumes the output buffer size matches the input buffer size, which leads to invalid memory operations and heap corruption.

Impact Analysis

The vulnerability can cause denial of service by crashing applications that use the affected driver. Additionally, it has the potential to allow code execution in user space, which could be exploited by an attacker with local access to the system.
