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 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.
