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 Scientific Linux 4 provide both the FreeType 1 and FreeType 2 font engines. The freetype packages for Scientific Linux 5 and 6 provide only the FreeType 2 font engine.
Multiple input validation flaws were found in the way FreeType processed bitmap font files. If a specially crafted font file was loaded by an application linked against FreeType, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-3256)
Note: These issues only affected the FreeType 2 font engine.
Users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues. The X server must be restarted (log out, then log back in) for this update to take effect.
