CVE-2012-1142: 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 computation of advance width values for certain glyph outlines. A remote attacker could provide a specially-crafted TrueType 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.
