Security Fixes
- CVE-2012-1134, CVE-2012-1136, CVE-2012-1142, CVE-2012-1144
- Multiple flaws were found in the way FreeType handled TrueType Font (TTF), Glyph Bitmap Distribution Format (BDF), Windows .fnt and .fon, and PostScript Type 1 fonts. 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.
