15 Synopsis
16 ========
17
18 Multiple heap-based buffer overflows in CDF might result in the
19 execution of arbitrary code.
20
21 Background
22 ==========
23
24 CDF is a library for the Common Data Format which is a self-describing
25 data format for the storage and manipulation of scalar and
26 multidimensional data. It is developed by the NASA.

36 Description
37 ===========
38
39 Leon Juranic reported multiple heap-based buffer overflows for instance
40 in the ReadAEDRList64(), SearchForRecord_r_64(), LastRecord64(), and
41 CDFsel64() functions.
42
43 Impact
44 ======
45
46 A remote attacker could entice a user to open a specially crafted CDF
47 file, possibly resulting in the execution of arbitrary code with the
48 privileges of the user running the application, or a Denial of Service.
49
50 Workaround
51 ==========
52
53 There is no known workaround at this time.
54
55 Resolution
56 ==========
57
