Stack-based buffer overflow in FontForge 20100501 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long CHARSET_REGISTRY header in a BDF font file.

The Rocky Linux 9.6 host has a package installed that is affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_1397 advisory.

    This advisory aggregates security fixes for the fontforge SRPM in CIQ LTS 9.6. It addresses 5 CVEs:
    CVE-2024-25082, CVE-2024-25081, CVE-2025-50949, CVE-2020-5395, CVE-2010-4259.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Stack-based buffer overflow in FontForge 20100501 allows remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code via a long CHARSET_REGISTRY header in a BDF font     file. (CVE-2010-4259)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-201201-08 (FontForge: User-assisted execution of arbitrary code)

    FontForge is vulnerable to an error when processing the       'CHARSET_REGISTRY' header in font files, which could cause a stack-based       buffer overflow.
  Impact :

    A remote attacker could entice a user to open a specially crafted BDF       file using FontForge font editor, possibly resulting in the remote       execution of arbitrary code with the privileges of the FontForge process,       or a Denial of Service (application crash).
  Workaround :

    There is no known workaround at this time.

Ulrik Persson reported a stack-based buffer overflow flaw in FontForge, a font editor. When processed a crafted Bitmap Distribution Format (BDF) FontForge could crash or execute arbitrary code with the privileges of the user running FontForge.

fixes CVE-2010-4259 crash. See bug for proof of concept to test with.
