Description Jan Lieskovsky 2012-03-06 13:44:27 EST
An out-of heap-based buffer read flaw was found in the way FreeType font rendering engine performed:
1) adding of properties,
2) parsing of properties,
3) checking if particular property is an atom

for 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.
