FontForge SFD File Parsing Improper Validation of Array Index 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 a write past the end of an allocated array. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-28563.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-014311 advisory.

    CVE-2025-15279:
    FontForge GUtils BMP 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 pixels within BMP 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-27517.
