CVE-2012-1140: Buffer Overflow

First published: Tue Mar 06 2012(Updated: )

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.
