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 vulnerabilities that allow remote code execution through memory corruption bugs in font file parsing. Specifically, a heap-based buffer overflow in BMP file parsing (CVE-2025-15279), a use-after-free in SFD file parsing (CVE-2025-15269), and a buffer overflow in SFD file parsing (CVE-2025-15275) have been identified. These vulnerabilities affect Red Hat Enterprise Linux 10.0 Extended Update Support and associated CodeReady Linux Builder packages. Red Hat has issued an important security advisory (RHSA-2026:2232) and provided updated packages to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code remotely on affected systems. This could lead to full system compromise depending on the privileges of the exploited process. The vulnerabilities are rated with a high security impact by Red Hat. There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated fontforge packages for Red Hat Enterprise Linux 10.0 Extended Update Support and related CodeReady Linux Builder variants. Users should apply these official security updates as described in Red Hat advisory RHSA-2026:2232 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor beyond applying the update.
