Background
==========
FreeType is a portable font engine.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

Description
===========
Multiple integer overflows exist in a variety of files (bdf/bdflib.c,
sfnt/ttcmap.c, cff/cffgload.c, base/ftmac.c).
Impact

execution of arbitrary code.
Workaround
==========
