19 execute arbitrary code.
20
21 Background
22 ==========
23

39
40 Impact
41 ======
42
43 A remote attacker could entice a user to open a specially crafted
44 document using Graphite or an application linked against Graphite
45 library, possibly resulting in execution of arbitrary code with the
46 privileges of the process or a Denial of Service condition.
