15 Synopsis
16 ========
17
18 xine-lib is vulnerable to multiple buffer overflows when processing
19 FLAC and ASF streams.
20
21 Background
22 ==========
23
24 xine-lib is the core library package for the xine media player.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 media-libs/xine-lib < 1.1.10.1 >= 1.1.10.1
33
34 Description
35 ===========
36
37 Damian Frizza and Alfredo Ortega (Core Security Technologies)
38 discovered a stack-based buffer overflow within the open_flac_file()
39 function in the file demux_flac.c when parsing tags within a FLAC file
40 (CVE-2008-0486). A buffer overflow when parsing ASF headers, which is
41 similar to CVE-2006-1664, has also been discovered.
42
43 Impact
44 ======
45
46 A remote attacker could entice a user to play specially crafted FLAC or
47 ASF video streams with a player using xine-lib, potentially resulting
48 in the execution of arbitrary code with the privileges of the user
49 running the player.
50
51 Workaround
52 ==========
53
54 There is no known workaround at this time.
55
56 Resolution
57 ==========
58
59 All xine-lib users should upgrade to the latest version:
60
61 # emerge --sync
62 # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.10.1"
