Remote Code Execution Vulnerability in FontForge Due to Parsing Flaw

CVE-2025-15270

What is CVE-2025-15270?

A vulnerability in FontForge exists due to improper validation while parsing SFD files, which allows remote attackers to execute arbitrary code. This issue arises when user-supplied data isn't correctly validated, leading to potential memory corruption through writes beyond the allocated array's boundary. Exploiting this flaw requires user interaction, as the target must visit a malicious page or open a compromised file. This compromise can put users at risk, executing code in the context of the current user, highlighting the importance of secure coding practices in file parsing.
