| <description> |
| <p> |
| iDEFENSE, Ariel Berkman and the MPlayer development team found |
| multiple vulnerabilities in MPlayer. These include potential heap |
| overflows in Real RTSP and pnm streaming code, stack overflows in MMST |
| streaming code and multiple buffer overflows in BMP demuxer and mp3lib |
| code. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could craft a malicious file or design a |
| malicious streaming server. Using MPlayer to view this file or connect |
| to this server could trigger an overflow and execute |
| attacker-controlled code. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </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_pre5-r5"</code> |
| </resolution> |
