    <p>
    Samba is a suite of SMB and CIFS client/server programs for UNIX.

  <description>
    <p>
    A format string vulnerability exists in the VFS module when handling
    AFS file systems and an infinite loop has been discovered when handling
    file rename operations.
    </p>
  </description>
  <impact type="normal">
    <p>
    A user with permission to write to a shared AFS file system may be able
    to compromise the smbd process and execute arbitrary code with the
    permissions of the daemon. The infinite loop could be abused to consume
    excessive resources on the smbd host, denying service to legitimate
    users.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Samba users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=net-fs/samba-3.0.24&quot;</code>
  </resolution>
