Description Huzaifa S. Sidhpurwala 2012-12-25 04:02:19 UTC 
A Null pointer de-reference flaw was found in the way Freetype font rendering engine handled Glyph bitmap distribution format (BDF) fonts. A remote attacker could provide a specially-crafted BDF font file, which once processed in an application linked against FreeType would lead to that application crash.
