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 remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - fontforge: Command injetion in help function uiutil.c (CVE-2017-17521)

  - 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)

  - FontForge 20161012 is vulnerable to a heap-based buffer over-read in PSCharStringToSplines (psread.c)     resulting in DoS or code execution via a crafted otf file. (CVE-2017-11568)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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.
