  <background>
    <p>
    Firebird is an open source relational database that runs on Linux,
    Windows, and various UNIX systems.
    </p>
  </background>
  <description>
    <p>
    A buffer overflow exists in three Firebird binaries (gds_inet_server,
    gds_lock_mgr, and gds_drop) that is exploitable by setting a large
    value to the INTERBASE environment variable.
    </p>
  </description>
  <impact type="high">
    <p>
    An attacker could control program execution, allowing privilege
    escalation to the UID of Firebird, full access to Firebird databases,
    and trojaning the Firebird binaries. An attacker could use this to
    compromise other user or root accounts.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround.
    </p>
  </workaround>
  <resolution>
    <p>
    All users should upgrade to the latest version of Firebird:
    </p>
    <code>
    # emerge sync
    
    # emerge -pv "&gt;=dev-db/firebird-1.5"
    # emerge "&gt;=dev-db/firebird-1.5"</code>
  </resolution>
