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) * fontforge: FontForge: Remote Code Execution via malicious SFD file parsing (CVE-2025-15270) 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 several critical security flaws that allow remote code execution through malformed font files. Specifically, CVE-2025-15279 involves a heap-based buffer overflow in BMP file parsing; CVE-2025-15269 is a use-after-free vulnerability in SFD file parsing; CVE-2025-15275 is a buffer overflow in SFD file parsing; and CVE-2025-15270 involves remote code execution via malicious SFD file parsing. These vulnerabilities affect Red Hat Enterprise Linux 8 and related CodeReady Linux Builder packages. Red Hat has released updated packages to fix these issues as detailed in advisory RHSA-2026:7677.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code remotely by supplying specially crafted font files. This could lead to full compromise of affected systems running vulnerable versions of FontForge on Red Hat Enterprise Linux 8. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated FontForge packages for Red Hat Enterprise Linux 8 and related CodeReady Linux Builder variants to address these vulnerabilities. Users should apply the security update described in advisory RHSA-2026:7677 promptly. For detailed update instructions, refer to https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor.
