Doc Text:
A flaw was found in FontForge. This heap-based buffer overflow vulnerability allows a remote attacker to execute arbitrary code on the system. The flaw occurs during the parsing of SFD (Spline Font Database) files due to insufficient validation of user-supplied data length. Successful exploitation requires user interaction, such as opening a specially crafted malicious SFD file.

Description OSIDB Bzimport 2025-12-31 08:01:36 UTC 
FontForge SFD File Parsing Heap-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 SFD 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 user. Was ZDI-CAN-28547.
