Heap-based buffer overflow in the Ins_SHZ function in ttinterp.c in FreeType 2.4.3 and earlier allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted SHZ bytecode instruction, related to TrueType opcodes, as demonstrated by a PDF document with a crafted embedded font.

Specially crafted font files could crash applications that use freetype2 to render the fonts (CVE-2010-3814, CVE-2010-3855).

The remote host is affected by the vulnerability described in GLSA-201201-09 (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 open a specially crafted font,       possibly resulting in the remote execution of arbitrary code with the       privileges of the user running the application, or a Denial of Service.
  Workaround :

    There is no known workaround at this time.

Specially crafted font files could crash applications that use freetype2 to render the fonts. (CVE-2010-3814 / CVE-2010-3855)

Multiple vulnerabilities were discovered and corrected in freetype2 :

An error within the 'Ins_SHZ()' function in src/truetype/ttinterp.c when handling the 'SHZ' bytecode instruction can be exploited to cause a crash and potentially execute arbitrary code via a specially crafted font (CVE-2010-3814).

An error exists in the 'ft_var_readpackedpoints()' function in src/truetype/ttgxvar.c when processing TrueType GX fonts and can be exploited to cause a heap-based buffer overflow via a specially crafted font (CVE-2010-3855).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

The updated packages have been patched to correct these issues.

Marc Schoenefeld 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 or possibly execute arbitrary code with user privileges. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.10 and 10.04 LTS.
(CVE-2010-3311)

Chris Evans discovered that FreeType did not correctly handle certain malformed TrueType font files. If a user were tricked into using a specially crafted TrueType file, a remote attacker could cause FreeType to crash or possibly execute arbitrary code with user privileges. This issue only affected Ubuntu 8.04 LTS, 9.10, 10.04 LTS and 10.10. (CVE-2010-3814)

It was discovered that FreeType did not correctly handle certain malformed TrueType font files. If a user were tricked into using a specially crafted TrueType file, a remote attacker could cause FreeType to crash or possibly execute arbitrary code with user privileges. (CVE-2010-3855).
