FontForge 20161012 is vulnerable to a buffer over-read in strnmatch (char.c) resulting in DoS or code execution via a crafted otf file, related to a call from the readttfcopyrights function in parsettf.c.

The remote Redhat Enterprise Linux 7 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)

  - 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)

  - FontForge 20161012 is vulnerable to a heap-based buffer over-read in readttfcopyrights (parsettf.c)     resulting in DoS or code execution via a crafted otf file. (CVE-2017-11569)

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 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)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3409-1 advisory.

    It was discovered that FontForge was vulnerable to a heap-based buffer over-read. A remote attacker could     use a crafted file to DoS or execute arbitrary code. (CVE-2017-11568, CVE-2017-11569, CVE-2017-11572)

    It was discovered that FontForge was vulnerable to a stack-based buffer overflow. A remote attacker could     use a crafted file to DoS or execute arbitrary code. (CVE-2017-11571)

    It was discovered that FontForge was vulnerable to a heap-based buffer overflow. A remote attacker could     use a crafted file to DoS or execute arbitrary code. (CVE-2017-11574)

    It was discovered that FontForge was vulnerable to a buffer over-read. A remote attacker could use a     crafted file to DoS or execute arbitrary code. (CVE-2017-11575, CVE-2017-11577)

    It was discovered that FontForge wasn't correctly checking the sign of a vector size. A remote attacker     could use a crafted file to DoS. (CVE-2017-11576)

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

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

It was discovered that FontForge, a font editor, did not correctly validate its input. An attacker could use this flaw by tricking a user into opening a maliciously crafted OpenType font file, thus causing a denial-of-service via application crash, or execution of arbitrary code.

FontForge is vulnerable to heap-based buffer over-read in several functions, resulting in DoS or code execution via a crafted otf file :

For Debian 7 'Wheezy', these problems have been fixed in version 0.0.20120101+git-2+deb7u1.

We recommend that you upgrade your fontforge packages.
