REDHAT-BUG-800593

First published: Tue Mar 06 2012(Updated: )

An out-of heap-based buffer read flaw was found in the way TrueType bytecode / opcode interpreter of the FreeType font rendering engine performed execution of NPUSHB and NPUSHW instructions. 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.
