Updated freetype packages that fix three security issues are now available for Red Hat Enterprise Linux 3.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

FreeType is a free, high-quality, portable font engine that can open and manage font files. It also loads, hints, and renders individual glyphs efficiently. The freetype packages for Red Hat Enterprise Linux 3 provide both the FreeType 1 and FreeType 2 font engines.

It was discovered that the FreeType font rendering engine improperly validated certain position values when processing input streams. If a user loaded a specially crafted font file with an application linked against FreeType, and the relevant font glyphs were subsequently rendered with the X FreeType library (libXft), it could trigger a heap-based buffer overflow in the libXft library, causing the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2010-3311)

An array index error was found in the way the FreeType font rendering engine processed certain PostScript Type 42 font files. If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2010-2806)

A stack overflow flaw was found in the way the FreeType font rendering engine processed PostScript Type 1 font files that contain nested Standard Encoding Accented Character (seac) calls. If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash. (CVE-2010-3054)

Note: All of the issues in this erratum only affect the FreeType 2 font engine.

Users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The X server must be restarted (log out, then log back in) for this update to take effect.

When loading specially crafted font files applications linked against freetype2 could crash or potentially even execute arbitrary code (CVE-2010-3311, CVE-2010-3053, CVE-2010-3054). This has been fixed.

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.

Updated freetype packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

FreeType is a free, high-quality, portable font engine that can open and manage font files. It also loads, hints, and renders individual glyphs efficiently. The freetype packages for Red Hat Enterprise Linux 4 provide both the FreeType 1 and FreeType 2 font engines. The freetype packages for Red Hat Enterprise Linux 5 provide only the FreeType 2 font engine.

If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2010-2808)

If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2010-2806)

A stack overflow flaw was found in the way the FreeType font rendering engine processed PostScript Type 1 font files that contain nested Standard Encoding Accented Character (seac) calls. If a user loaded a specially crafted font file with an application linked against FreeType, it could cause the application to crash. (CVE-2010-3054)

Note: All of the issues in this erratum only affect the FreeType 2 font engine.

Users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The X server must be restarted (log out, then log back in) for this update to take effect.

When loading specially crafted font files applications linked against freetype2 could crash or potentially even execute arbitrary code (CVE-2010-3311 / CVE-2010-3053 / CVE-2010-3054). This has been fixed.

A vulnerability was discovered and corrected in freetype2 :

Marc Schoenefeld found an input stream position error in the way FreeType font rendering engine processed input file streams. If a user loaded a specially crafted font file with an application linked against FreeType and relevant font glyphs were subsequently rendered with the X FreeType library (libXft), it could cause the application to crash or, possibly execute arbitrary code (integer overflow leading to heap-based buffer overflow in the libXft library) with the privileges of the user running the application. Different vulnerability than CVE-2010-1797 (CVE-2010-3311).

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 this issue.

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).
