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

+ OpenAFS is a distributed network filesystem.

+ <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 "&gt;=net-fs/openafs-1.4.4"</code>
