Ashlar-Vellum Graphite Stack-Based Buffer Overflow Vulnerability Leading to Remote Code Execution

A stack-based buffer overflow vulnerability has been identified in Ashlar-Vellum Graphite, specifically within the VC6 file parsing process. This issue arises from inadequate validation of user-supplied data lengths before they are copied to a stack-based buffer. As a result, remote attackers can execute arbitrary code on affected systems, but exploitation requires user interaction, such as opening a malicious file.

Impact

Exploitation of this vulnerability allows for arbitrary code execution on the affected system, with the executed code running in the context of the current process.

Remediation

Due to the nature of this vulnerability, the primary recommendation is to limit interactions with the product.
