| <description> |
| <p> |
| Nico Golde reported a stack-based buffer overflow when processing a MSN |
| packet with a UBX command containing a large UBX payload length field. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could send a specially crafted message, possibly |
| resulting in the execution of arbitrary code. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| Since TMSNC is no longer maintained, we recommend that users unmerge |
| the vulnerable package and switch to another console-based MSN client |
| such as CenterIM or Pebrot: |
| </p> |
| <code> |
| # emerge --unmerge "net-im/tmsnc"</code> |
