Description |
36 |
=========== |
37 |
|
38 |
oCERT reported that the Speex library does not properly validate the |
39 |
"mode" value it derives from Speex streams, allowing for array indexing |
40 |
vulnerabilities inside multiple player applications. Within Gentoo, |
41 |
xine-lib, VLC, gst-plugins-speex from the GStreamer Good Plug-ins, |
42 |
vorbis-tools, libfishsound, Sweep, SDL_sound, and speexdec were found |
43 |
to be vulnerable. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker could entice a user to open a specially crafted Speex |
49 |
file or network stream with an application listed above. This might |
50 |
lead to the execution of arbitrary code with privileges of the user |
51 |
playing the file. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All Speex users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=media-libs/speex-1.2_beta3_p2" |
65 |
