Scientific Linux Security Update : freetype on SL6.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.

The X server must be restarted (log out, then log back in) for this
update to take effect.
