Synopsis |
16 |
======== |
17 |
|
18 |
ModPlug contains several buffer overflows that could lead to the |
19 |
execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
ModPlug is a library for playing MOD-like music. |

Description |
39 |
=========== |
40 |
|
41 |
Two vulnerabilities have been reported in ModPlug: |
42 |
|
43 |
* dummy reported an integer overflow in the CSoundFile::ReadMed() |
44 |
function when processing a MED file with a crafted song comment or |
45 |
song name, which triggers a heap-based buffer overflow |
46 |
(CVE-2009-1438). |
47 |
|
48 |
* Manfred Tremmel and Stanislav Brabec reported a buffer overflow in |
49 |
the PATinst() function when processing a long instrument name |
50 |
(CVE-2009-1513). |
51 |
|
52 |
The GStreamer Bad plug-ins (gst-plugins-bad) before 0.10.11 built a |
53 |
vulnerable copy of ModPlug. |
54 |
|
55 |
Impact |
56 |
====== |
57 |
|
58 |
A remote attacker could entice a user to read specially crafted files, |
59 |
possibly resulting in the execution of arbitrary code with the |
60 |
privileges of the user running the application. |
61 |
|
62 |
Workaround |
63 |
========== |
64 |
|
65 |
There is no known workaround at this time. |
66 |
|
67 |
Resolution |
68 |
========== |
69 |
|
70 |
All ModPlug users should upgrade to the latest version: |
71 |
|
72 |
# emerge --sync |
73 |
# emerge --ask --oneshot --verbose ">=media-libs/libmodplug-0.8.7" |
74 |
|
75 |
gst-plugins-bad 0.10.11 and later versions do not include the ModPlug |
76 |
plug-in (it has been moved to media-plugins/gst-plugins-modplug). All |
77 |
gst-plugins-bad users should upgrade to the latest version and install |
78 |
media-plugins/gst-plugins-modplug: |
79 |
|
80 |
# emerge --sync |
81 |
# emerge --ask --oneshot -v ">=media-libs/gst-plugins-bad-0.10.11" |
82 |
# emerge --ask --verbose "media-plugins/gst-plugins-modplug" |
83 |
