| run arbitrary code, crash the program or perform DoS by CPU and disk |

| <p> |
| Ethereal is a feature rich network protocol analyzer. |
| </p> |
| </background> |
| <description> |
| <p> |
| There are multiple vulnerabilities in versions of Ethereal earlier |
| than 0.10.9, including: |
| </p> |
| <ul> |
| <li>The COPS dissector could go into |
| an infinite loop (CAN-2005-0006).</li> |
| <li>The DLSw dissector could |
| cause an assertion, making Ethereal exit prematurely |
| (CAN-2005-0007).</li> |
| <li>The DNP dissector could cause memory |
| corruption (CAN-2005-0008).</li> |
| <li>The Gnutella dissector could cause |
| an assertion, making Ethereal exit prematurely (CAN-2005-0009).</li> |
| <li>The MMSE dissector could free statically-allocated memory |
| (CAN-2005-0010).</li> |
| <li>The X11 dissector is vulnerable to a string |
| buffer overflow (CAN-2005-0084).</li> |
| </ul> |
| </description> |
| <impact type="high"> |
| <p> |
| An attacker might be able to use these vulnerabilities to crash |
| Ethereal, perform DoS by CPU and disk space utilization or even execute |
| arbitrary code with the permissions of the user running Ethereal, which |
| could be the root user. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| For a temporary workaround you can disable all affected protocol |
| dissectors by selecting Analyze->Enabled Protocols... and deselecting |
| them from the list. However, it is strongly recommended to upgrade to |
| the latest stable version. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Ethereal users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-analyzer/ethereal-0.10.9"</code> |
| </resolution> |
