| <background> |
| <p>A suite of applications that implement the Kerberos 5 network protocol |
| from MIT. |

| <description> |
| <p>Multiple vulnerabilities have been discovered in MIT Kerberos 5 |
| Applications: |
| </p> |
| |
| <ul> |
| <li>An error in the FTP daemon prevents it from dropping its initial |
| effective group identifier (CVE-2011-1526). |
| </li> |
| <li>A boundary error in the telnet daemon and client could cause a buffer |
| overflow (CVE-2011-4862). |
| </li> |
| </ul> |
| |
| </description> |
| <impact type="normal"> |
| <p>An unauthenticated remote attacker may be able to execute arbitrary code |
| with the privileges of the user running the telnet daemon or client. |
| Furthermore, an authenticated remote attacker may be able to read or |
| write files owned by the same group as the effective group of the FTP |
| daemon. |
| </p> |
| </impact> |
| <workaround> |
| <p>There is no known workaround at this time.</p> |
| </workaround> |
| <resolution> |
| <p>All MIT Kerberos 5 Applications users should upgrade to the latest |
| version: |
| </p> |
