FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.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.

  - freetype: heap-based buffer overflow related to the t1_builder_close_contour function (CVE-2017-8287)

  - The parse_encoding function in type1/t1load.c in FreeType before 2.5.3 allows remote attackers to cause a     denial of service (infinite loop) via a broken number-with-base in a Postscript stream, as demonstrated     by 8#garbage. (CVE-2014-9745)

  - The (1) t1_parse_font_matrix function in type1/t1load.c, (2) cid_parse_font_matrix function in     cid/cidload.c, (3) t42_parse_font_matrix function in type42/t42parse.c, and (4) ps_parser_load_field     function in psaux/psobjs.c in FreeType before 2.5.4 do not check return values, which allows remote     attackers to cause a denial of service (uninitialized memory access and application crash) or possibly     have unspecified other impact via a crafted font. (CVE-2014-9746)

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

According to the versions of the freetype package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - FreeType 2 before 2017-03-24 has an out-of-bounds write     caused by a heap-based buffer overflow related to the     t1_decoder_parse_charstrings function in     psaux/t1decode.c.(CVE-2017-8105)

An update of the freetype2 package has been released.

This update for freetype2 fixes the following issues: Security issue fixed :

  - CVE-2016-10244: The parse_charstrings function in     type1/t1load.c did not ensure that a font contains a     glyph name, which allowed remote attackers to cause a     denial of service (heap-based buffer over-read) or     possibly have unspecified other impact via a crafted     file (bsc#1028103).

  - CVE-2017-8105: Fixed an out-of-bounds write caused by a     heap-based buffer overflow related to the     t1_decoder_parse_charstrings function in     psaux/t1decode.ca (bsc#1035807)

  - CVE-2017-8287: an out-of-bounds write caused by a     heap-based buffer overflow related to the     t1_builder_close_contour function in psaux/psobjs.c     (bsc#1036457)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201706-14 (FreeType: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in FreeType. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to use a specially crafted font       file using FreeType, possibly resulting in execution of arbitrary code       with the privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Werner Lemberg reports :

CVE-2017-8105, CVE-2017-8287: Older FreeType versions have out-of-bounds writes caused by heap-based buffer overflows related to Type 1 fonts.

It was discovered that FreeType did not correctly handle certain malformed font files. If a user were tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash, resulting in a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3282-1 advisory.

    It was discovered that FreeType did not correctly handle certain malformed font files. If a user were     tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash,     resulting in a denial of service, or possibly execute arbitrary code.

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.

Several vulnerabilities were discovered in Freetype. Opening malformed fonts may result in denial of service or the execution of arbitrary code.

It was found that an out of bounds write caused by a heap-based buffer overflow could be triggered in freetype via a crafted font.

This update also reverts the fix for CVE-2016-10328, as it was determined that freetype 2.4.9 is not affected by that issue.

For Debian 7 'Wheezy', these problems have been fixed in version 2.4.9-1.1+deb7u6.

We recommend that you upgrade your freetype packages.
