| <p> |
| Sven Tantau discovered a heap overflow in the code handling the |
| strf chunk of PCM audio streams. |

| <impact type="normal"> |
| <p> |
| An attacker could craft a malicious video or audio file which, |
| when opened using MPlayer, would end up executing arbitrary code on the |
| victim's computer with the permissions of the user running MPlayer. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| You can mitigate the issue by adding "ac=-pcm," to your MPlayer |
| configuration file (note that this will prevent you from playing |
| uncompressed audio). |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All MPlayer users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre7-r1"</code> |
