freetype is vulnerable to arbitrary code execution. The vulnerability exists as 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.
