Unspecified vulnerability in FreeType 2.3.9, and other versions before 2.4.2, allows remote attackers to cause a denial of service via vectors involving nested Standard Encoding Accented Character (aka seac) calls, related to psaux.h, cffgload.c, cffgload.h, and t1decode.c.

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).

From Red Hat Security Advisory 2010:0737 :

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.

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)

A stack-based buffer overflow flaw was found in the way the FreeType font rendering engine processed some PostScript Type 1 fonts. 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)

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.

Multiple vulnerabilities has been found and corrected in freetype2 :

The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file (CVE-2010-2805).

Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow (CVE-2010-2806).

FreeType before 2.4.2 uses incorrect integer data types during bounds checking, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file (CVE-2010-2807).

Buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Adobe Type 1 Mac Font File (aka LWFN) font (CVE-2010-2808).

bdf/bdflib.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) via a crafted BDF font file, related to an attempted modification of a value in a static string (CVE-2010-3053).

Unspecified vulnerability in FreeType 2.3.9, and other versions before 2.4.2, allows remote attackers to cause a denial of service via vectors involving nested Standard Encoding Accented Character (aka seac) calls, related to psaux.h, cffgload.c, cffgload.h, and t1decode.c (CVE-2010-3054).
