Vulnerability from cvelistv5 – Published: 2025-12-31 06:59 – Updated: 2025-12-31 16:58

Title

FontForge PFB File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability

Summary

FontForge PFB File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of FontForge. 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 PFB files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-28546.

Severity ?

8.8 (High)
