Red Hat Security Advisory 2011-1402-01 - 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. 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.
