  <title>Samba: Multiple vulnerabilities</title>
  <synopsis>
    Samba is vulnerable to a buffer overflow that could lead to execution of
    arbitrary code (CAN-2004-0882). Another flaw in Samba may allow a remote
    attacker to cause a Denial of Service by excessive consumption of CPU
    cycles (CAN-2004-0930).

  <background>
    <p>
    Samba is a freely available SMB/CIFS implementation which allows
    seamless interoperability of file and print services to other SMB/CIFS
    clients.
    </p>

  <description>
    <p>
    Samba fails to do proper bounds checking when handling
    TRANSACT2_QFILEPATHINFO replies. Additionally an input validation flaw
    exists in ms_fnmatch.c when matching filenames that contain wildcards.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker may be able to execute arbitrary code with the permissions
    of the user running Samba. A remote attacker may also be able to cause
    an abnormal consumption of CPU resources, resulting in slower
    performance of the server or even a Denial of Service.
    </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 "&gt;=net-fs/samba-3.0.8"</code>
  </resolution>
