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
FontForge contains multiple critical security flaws that allow remote code execution through heap-based buffer overflow and use-after-free vulnerabilities during parsing of BMP and SFD font files. These vulnerabilities are tracked under CVE-2025-15269, CVE-2025-15275, and CVE-2025-15279. Red Hat Product Security has released an important security update (RHSA-2026:2039) for Red Hat Enterprise Linux 9 CodeReady Linux Builder packages to fix these issues. The advisory references specific bugzilla entries for each CVE and provides updated packages for multiple architectures.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code on affected systems by supplying specially crafted BMP or SFD font files. This poses a high security risk as it may lead to full system compromise. The vulnerabilities affect the font parsing functionality of FontForge in Red Hat Enterprise Linux 9 CodeReady Linux Builder, impacting multiple CPU architectures.
Mitigation Recommendations
Red Hat has released updated FontForge packages that address these vulnerabilities. Users of Red Hat Enterprise Linux 9 CodeReady Linux Builder should apply the security update described in advisory RHSA-2026:2039 promptly. Detailed update instructions are available at https://access.redhat.com/articles/11258. No additional mitigations are indicated by the vendor advisory.
