Description Jan Lieskovsky 2012-03-06 18:56:54 UTC 
An out-of heap-based buffer read flaw was found in the way auxiliary PostScript driver of the FreeType font rendering engine performed conversion of certain PostScript font objects. A remote attacker could provide a specially-crafted PostScript font file, which once opened in an application linked against FreeType would lead to that application crash.
