Description
Ashlar-Vellum Graphite VC6 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Graphite. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of VC6 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25477.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a heap-based buffer overflow in Ashlar-Vellum Graphite's VC6 file parsing. It occurs because the software does not properly validate the length of user-supplied data before copying it into a heap buffer. This flaw allows remote attackers to execute arbitrary code by tricking a user into opening a malicious file or visiting a malicious page.


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker to execute arbitrary code on your system with the privileges of the current process. This could lead to unauthorized actions such as installing malware, stealing data, or disrupting system operations. Exploitation requires user interaction, such as opening a malicious file or visiting a malicious webpage.
