Ashlar-Vellum Cobalt Integer Overflow Vulnerability Leading to Remote Code Execution

A remote code execution vulnerability has been identified in Ashlar-Vellum Cobalt, specifically within the LI file parsing component. This issue arises from improper validation of user-supplied data, allowing for an integer overflow that occurs before buffer allocation. As a result, an attacker can execute arbitrary code in the context of the current process. Exploitation of this vulnerability requires user interaction, as the target must open a malicious LI 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.
