CVE-2025-15271
Description
A flaw was found in FontForge. This vulnerability allows a remote attacker to execute arbitrary code on affected installations. Exploitation requires user interaction, such as opening a malicious SFD (Spline Font Database) file. The issue arises from improper validation of user-supplied data during SFD file parsing, which can lead to a write past the end of an allocated memory array, enabling arbitrary code execution in the context of the current user.
Statement
This vulnerability is rated Important for Red Hat products as it allows for remote code execution in FontForge. Exploitation requires user interaction, specifically opening a specially crafted SFD file. This affects FontForge as shipped in Red Hat Enterprise Linux 6 ELS, 7 ELS, 8, 9, 10, Fedora, and Red Hat In-Vehicle OS.
Mitigation
To mitigate this issue, users should exercise caution when handling SFD (Spline Font Database) files from untrusted sources. Avoid opening SFD files from unknown or suspicious origins. If FontForge is not actively used, consider removing the `fontforge` package to eliminate the attack surface. This can be done using `sudo dnf remove fontforge` on Red Hat Enterprise Linux 8, 9, 10, and Fedora, or `sudo yum remove fontforge` on Red Hat Enterprise Linux 6 ELS and 7 ELS. Removing this package will remove FontForge functionality.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
