Red Hat Security Advisory: fontforge security update
FontForge is a font editor for outline and bitmap fonts. It supports a range of font formats, including PostScript (ASCII and binary Type 1, some Type 3 and Type 0), TrueType, OpenType (Type2) and CID-keyed fonts. Security Fix(es): * fontforge: FontForge: Remote Code Execution via heap-based buffer overflow in BMP file parsing (CVE-2025-15279) * fontforge: FontForge: Remote Code Execution via Use-After-Free in SFD file parsing (CVE-2025-15269) * fontforge: FontForge: Arbitrary code execution via SFD file parsing buffer overflow (CVE-2025-15275) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
Multiple vulnerabilities in FontForge affect its parsing of BMP and SFD font files. CVE-2025-15279 is a heap-based buffer overflow in BMP file parsing that allows remote code execution. CVE-2025-15269 is a use-after-free vulnerability in SFD file parsing leading to remote code execution. CVE-2025-15275 is a buffer overflow in SFD file parsing that enables arbitrary code execution. These issues are addressed by a security update released by Red Hat for Red Hat Enterprise Linux 10 and associated CodeReady Linux Builder variants. The advisory references fixes for these CVEs and provides updated packages for multiple architectures.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code remotely by crafting malicious BMP or SFD font files. This poses a high security risk as it could lead to full system compromise on affected systems running vulnerable versions of FontForge within Red Hat Enterprise Linux 10 environments.
Mitigation Recommendations
Red Hat has released an official security update (RHSA-2026:2230) that fixes the vulnerabilities in FontForge. Users should apply the updated packages provided by Red Hat for Red Hat Enterprise Linux 10 and CodeReady Linux Builder to remediate these issues. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor advisory.
