3. Description:
FreeType is a free, high-quality, portable font engine that can open and
manage font files, as well as efficiently load, hint and render individual
glyphs.
Multiple flaws were discovered in FreeType's Printer Font Binary (PFB)
font-file format parser. If a user loaded a carefully crafted font-file
with a program linked against FreeType, it could cause the application to
crash, or possibly execute arbitrary code. (CVE-2008-1806, CVE-2008-1807,
CVE-2008-1808)
Note: the flaw in FreeType's TrueType Font (TTF) font-file format parser,
covered by CVE-2008-1808, did not affect the freetype packages as shipped
in Red Hat Enterprise Linux 3, 4, and 5, as they are not compiled with TTF
Byte Code Interpreter (BCI) support.
Users of freetype should upgrade to these updated packages, which contain
backported patches to resolve these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at

This update has been rated as having important security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64

3. Description:
FreeType is a free, high-quality, portable font engine that can open and
manage font files, as well as efficiently load, hint and render individual
glyphs.
Multiple flaws were discovered in FreeType's Printer Font Binary (PFB) and
TrueType Font (TTF) font-file format parsers. If a user loaded a carefully
crafted font-file with a program linked against FreeType, it could cause
the application to crash, or possibly execute arbitrary code.
(CVE-2008-1806, CVE-2008-1807, CVE-2008-1808)
Note: the flaw in FreeType's TrueType Font (TTF) font-file format parser,
covered by CVE-2008-1808, only affected the FreeType 1 library (libttf),
shipped in the freetype packages in Red Hat Enterprise Linux 2.1. The
FreeType 2 library (libfreetype) is not affected, as it is not compiled
with TTF Byte Code Interpreter (BCI) support.
Users of freetype should upgrade to these updated packages, which contain
backported patches to resolve these issues.

3. Description:
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. These packages provide both the FreeType 1 and FreeType 2 font
engines.
An integer overflow flaw was found in the way the FreeType font engine
processed font files. If a user loaded a carefully-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-2010-2500)
Several buffer overflow flaws were found in the FreeType demo applications.
If a user loaded a carefully-crafted font file with a demo application, it
could cause the application to crash or, possibly, execute arbitrary code
with the privileges of the user running the application. (CVE-2010-2527,
CVE-2010-2541)
Red Hat would like to thank Robert Swiecki of the Google Security Team for
the discovery of the CVE-2010-2500 and CVE-2010-2527 issues.
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

3. Description:
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.

3. Description:
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. These packages provide the FreeType 2 font engine.
It was found 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, it
could cause the application to crash or, possibly, execute arbitrary code
with the privileges of the user running the application. (CVE-2010-2805,
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)
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.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

3. Description:
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 and 6 provide only the FreeType 2 font engine.
A heap-based buffer overflow flaw was found in the way the FreeType font
rendering engine processed certain TrueType GX 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-2010-3855)
