Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A buffer overflow was found in MPlayer's RTSP plugin that could lead to |
| 19 |

| 20 |
|
| 21 |
Background |
| 22 |
========== |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
When checking for matching asm rules in the asmrp.c code, the results |
| 38 |
are stored in a fixed-size array without boundary checks which may |
| 39 |
allow a buffer overflow. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
An attacker can entice a user to connect to a manipulated RTSP server |
| 45 |
resulting in a Denial of Service and possibly execution of arbitrary |
| 46 |
code. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All MPlayer users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_rc1-r2" |
