15 Synopsis
16 ========
17
18 A buffer overflow vulnerability in Win32 Codecs can potentially allow
19 for user-assisted arbitrary code execution.
20
21 Background
22 ==========
23
24 Win32 Codecs is a set of Windows audio and video playback codecs.
25
26 Affected packages
27 =================
28
29 -------------------------------------------------------------------
30 Package / Vulnerable / Unaffected
31 -------------------------------------------------------------------
32 1 media-libs/win32codecs <= 20071007-r4 Vulnerable!
33 -------------------------------------------------------------------
34 NOTE: Certain packages are still vulnerable. Users should migrate
35 to another package if one is available or wait for the
36 existing packages to be marked stable by their
37 architecture maintainers.
38
39 Description
40 ===========
41
42 A heap-based buffer overflow exists when handling Shockwave Flash
43 files.
44
45 Impact
46 ======
47
48 A remote attacker could entice a user to open a specially crafted Flash
49 file using a package linked against Win32 Codecs, possibly resulting in
50 execution of arbitrary code with the privileges of the process or a
51 Denial of Service condition.
52
53 Workaround
54 ==========
55
56 There is no known workaround at this time.
57
58 Resolution
59 ==========
60
61 Gentoo has discontinued support for Win32 Codecs. We recommend that
62 users unmerge Win32 Codecs:
63
64 # emerge --unmerge "media-libs/win32codecs"
