Description Huzaifa S. Sidhpurwala 2012-12-25 04:25:02 UTC
An out-of heap-based buffer write flaw was found in the way FreeType font rendering engine performed parsing of glyph information and relevant bitmaps for glyph bitmap distribution format (BDF). A remote attacker could provide a specially-crafted 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.
