15 Synopsis
16 ========
17
18 xine-ui improperly handles format strings, possibly allowing for the
19 execution of arbitrary code.
20
21 Background
22 ==========
23
24 xine-ui is a skin-based user interface for xine. xine is a free
25 multimedia player. It plays CDs, DVDs, and VCDs, and can also decode
26 other common multimedia formats.

35
36 Description
37 ===========
38
39 Due to the improper handling and use of format strings, the

41 to memory.
42
43 Impact
44 ======
45
46 An attacker could entice a user to open a specially crafted media file
47 with xine-ui, and possibly execute arbitrary code.

52 There is no known workaround at this time.
53
54 Resolution
55 ==========
