CVE-2012-1133: Buffer Overflow

First published: Tue Mar 06 2012(Updated: )

An out-of heap-based buffer write flaw was found in the way FreeType font rendering engine performed parsing of glyph information and bitmaps for certain glyph bitmap distribution format (BDF) fonts. A remote attacker could provide a specially-crafted BDF font file, which once opened in an application linked against FreeType would lead to that application crash, or, potentially, arbitrary code execution with the privileges of the user running the application.
