| <impact type="normal"> |
| <p> |
| A remote attacker could exploit these vulnerabilities by sending |
| specially crafted packets on a network being monitored by Wireshark or |
| by enticing a user to read a malformed packet trace file, causing a |
| Denial of Service. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Wireshark users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.3"</code> |
