| Samba client messaging functions, allowing a Linux desktop to |
| communicate with a Microsoft Windows computer that runs Winpopup. |

| <description> |
| <p> |
| Stephen Dranger discovered that LinPopUp contains a buffer |
| overflow in string.c, triggered when replying to a remote user message. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could craft a malicious message that, when |
| replied using LinPopUp, would exploit the buffer overflow. This would |
| result in the execution of arbitrary code with the privileges of the |
| user running LinPopUp. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All LinPopUp users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-im/linpopup-2.0.4-r1"</code> |
