| Fetchmail versions 6.2.4 and earlier can be crashed by sending a |
| specially-crafted email to a fetchmail user. This problem occurs because |
| Fetchmail does not properly allocate memory for long lines in an incoming |
| email. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| Fetchmail users who receive a malicious email may have their fetchmail |
| program crash. |
