Doc Text:
A flaw was found in FontForge. A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted SFD file. This issue arises from improper validation of user-supplied data during SFD file parsing, leading to deserialization of untrusted data. Successful exploitation could result in arbitrary code execution in the context of the current process.

Description OSIDB Bzimport 2025-12-31 08:01:20 UTC 
FontForge SFD File Parsing Deserialization of Untrusted Data 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 SFD files. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28198.
