Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Multiple vulnerabilities have been reported in MPlayer: |
| 40 |
|
| 41 |
* A stack-based buffer overflow was found in the str_read_packet() |
| 42 |
function in libavformat/psxstr.c when processing crafted STR files |
| 43 |
that interleave audio and video sectors (CVE-2008-3162). |
| 44 |
|
| 45 |
* Felipe Andres Manzano reported multiple integer underflows in the |
| 46 |
demux_real_fill_buffer() function in demux_real.c when processing |
| 47 |
crafted Real Media files that cause the stream_read() function to |
| 48 |
read or write arbitrary memory (CVE-2008-3827). |
| 49 |
|
| 50 |
* Tobias Klein reported a stack-based buffer overflow in the |
| 51 |
demux_open_vqf() function in libmpdemux/demux_vqf.c when processing |
| 52 |
malformed TwinVQ files (CVE-2008-5616). |
| 53 |
|
| 54 |
Impact |
| 55 |
====== |
| 56 |
|
| 57 |
A remote attacker could entice a user to open a specially crafted STR, |
| 58 |
Real Media, or TwinVQ file to execute arbitrary code or cause a Denial |
| 59 |
of Service. |
| 60 |
|
| 61 |
Workaround |
| 62 |
========== |
| 63 |
|
| 64 |
