| <title>OpenAFS: Privilege escalation</title> |
| <synopsis> |
| OpenAFS is subject to a design flaw that could allow privilege escalation |
| on the client. |

| <background> |
| <p> |
| OpenAFS is a distributed network filesystem. |

| <description> |
| <p> |
| Benjamin Bennett discovered that the OpenAFS client contains a design |
| flaw where cache managers do not use authenticated server connections |
| when performing actions not requested by a user. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| If setuid is enabled on the client cells, an attacker can supply a fake |
| FetchStatus reply that sets setuid and root ownership of a file being |
| executed. This could provide root access on the client. Remote attacks |
| may be possible if an attacker can entice a user to execute a known |
| file. Note that setuid is enabled by default in versions of OpenAFS |
| prior to 1.4.4. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| Disable the setuid functionality on all client cells. This is now the |
| default configuration in OpenAFS. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All OpenAFS users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-fs/openafs-1.4.4"</code> |
| </resolution> |
