Scientific Linux Security Update : freetype on SL3.x, SL4.x, SL5.x i386/x86_64

high Nessus Plugin ID 60861

Synopsis

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

Description

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) (SLF4 and SLF5 only)

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.

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

Solution

Update the affected packages.
