Description Jan Lieskovsky 2011-11-14 14:24:44 UTC 
Multiple security flaws (multiple unsanitized invalid user input cases and one integer overflow flaw) were found in the way FreeType, the font rendering engine performed loading of CID-keyed (composite multibyte) Type 1 fonts. A remote attacker could provide a specially-crafted font file, which once opened in an application linked against freetype could lead to crash, or, potentially arbitrary code execution with the privileges of the user running the application.
