|
|
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.

|
|
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>
