FontForge Heap-Based Buffer Overflow Vulnerability in SFD File Parsing Allowing Remote Code Execution

A heap-based buffer overflow vulnerability has been identified in FontForge, specifically within the SFD file parsing process. This issue arises from inadequate validation of user-supplied data lengths before copying them to a heap-based buffer. As a result, remote attackers can execute arbitrary code on affected installations of FontForge, but user interaction is required to exploit this vulnerability by opening a malicious SFD 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 user.

Remediation

Due to the nature of this vulnerability, the recommended mitigation strategy is to limit interactions with the product.
