Description Jan Lieskovsky 2012-03-06 13:59:12 EST
An integer divide by zero was found in the way FreeType font rendering engine performed arithmetic computations for certain fonts. 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.
