Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple vulnerabilities, including remotely exploitable buffer |
| 22 |
overflows, have been found in code common to MPlayer and the xine |
| 23 |
library. |
| 24 |
|
| 25 |
Background |
| 26 |
========== |
| 27 |
|
| 28 |
MPlayer is a movie player capable of handling multiple multimedia file |
| 29 |
formats. xine-lib is a multimedia player library used by several |
| 30 |
graphical user interfaces, including xine-ui. They both use the same |
| 31 |
code to handle Real-Time Streaming Protocol (RTSP) streams from |
| 32 |
RealNetworks servers. |
| 33 |
|
| 34 |
Affected packages |
| 35 |
================= |
| 36 |
|
| 37 |
------------------------------------------------------------------- |
| 38 |
Package / Vulnerable / Unaffected |
| 39 |
------------------------------------------------------------------- |
| 40 |
1 media-video/mplayer < 1.0_pre4 >= 1.0_pre4 |
| 41 |
<= 0.92-r1 |
| 42 |
2 media-libs/xine-lib < 1_rc4 >= 1_rc4 |

Description |
| 46 |
=========== |
| 47 |
|
| 48 |
Multiple vulnerabilities have been found and fixed in the RTSP handling |
| 49 |
code common to recent versions of these two packages. These |
| 50 |
vulnerabilities include several remotely exploitable buffer overflows. |
| 51 |
|
| 52 |
Impact |
| 53 |
====== |
| 54 |
|
| 55 |
A remote attacker, posing as a RTSP stream server, can execute |
| 56 |
arbitrary code with the rights of the user of the software playing the |
| 57 |
stream (MPlayer or any player using xine-lib). Another attacker may |
| 58 |
entice a user to use a maliciously crafted URL or playlist to achieve |
| 59 |
the same results. |
| 60 |
|
| 61 |
Workaround |
| 62 |
========== |
| 63 |
|
| 64 |
For MPlayer, there is no known workaround at this time. For xine-lib, |
| 65 |
you can delete the xineplug_inp_rtsp.so file. |
| 66 |
|
| 67 |
Resolution |
| 68 |
========== |
| 69 |
|
| 70 |
All users should upgrade to non-vulnerable versions of MPlayer and |
| 71 |
xine-lib: |
| 72 |
|
| 73 |
# emerge sync |
| 74 |
|
| 75 |
# emerge -pv ">=media-video/mplayer-1.0_pre4" |
| 76 |
# emerge ">=media-video/mplayer-1.0_pre4" |
| 77 |
|
| 78 |
# emerge -pv ">=media-libs/xine-lib-1_rc4" |
| 79 |
# emerge ">=media-libs/xine-lib-1_rc4" |
| 80 |
