Description Jan Lieskovsky 2012-03-06 13:48:53 EST
An out-of heap-based buffer read flaw was found in the way FreeType font rendering engine retrieved properties information from Portable Compiled Format (PCF) bitmap font files. A remote attacker could provide a specially-crafted PCF font file, which once opened in an application linked against FreeType would lead to that application crash.

Comment 7 Tomas Hoger 2012-03-15 12:37:55 EDT
The problem here is in pcf_get_properties(), which does not ensure that a string read form PCF font file is properly NUL terminated before passing it to strdup. This may possibly cause program crash.
