  * New upstream security/bugfix release.

    + Shore up GRANT ... WITH ADMIN OPTION restrictions (Noah Misch)

      Granting a role without ADMIN OPTION is supposed to prevent the grantee
      from adding or removing members from the granted role, but this
      restriction was easily bypassed by doing SET ROLE first. The security
      impact is mostly that a role member can revoke the access of others,
      contrary to the wishes of his grantor. Unapproved role member additions
      are a lesser concern, since an uncooperative role member could provide
      most of his rights to others anyway by creating views or SECURITY
      DEFINER functions. (CVE-2014-0060)

    + Prevent privilege escalation via manual calls to PL validator functions
      (Andres Freund)

      The primary role of PL validator functions is to be called implicitly
      during CREATE FUNCTION, but they are also normal SQL functions that a
      user can call explicitly. Calling a validator on a function actually
      written in some other language was not checked for and could be
      exploited for privilege-escalation purposes. The fix involves adding a
      call to a privilege-checking function in each validator function.
      Non-core procedural languages will also need to make this change to
      their own validator functions, if any. (CVE-2014-0061)

    + Avoid multiple name lookups during table and index DDL (Robert Haas,
      Andres Freund)

      If the name lookups come to different conclusions due to concurrent
      activity, we might perform some parts of the DDL on a different table
      than other parts. At least in the case of CREATE INDEX, this can be used
      to cause the permissions checks to be performed against a different
      table than the index creation, allowing for a privilege escalation
      attack. (CVE-2014-0062)

    + Prevent buffer overrun with long datetime strings (Noah Misch)

      The MAXDATELEN constant was too small for the longest possible value of
      type interval, allowing a buffer overrun in interval_out(). Although the
      datetime input functions were more careful about avoiding buffer
      overrun, the limit was short enough to cause them to reject some valid
      inputs, such as input containing a very long timezone name. The ecpg
      library contained these vulnerabilities along with some of its own.
      (CVE-2014-0063)

    + Prevent buffer overrun due to integer overflow in size calculations
      (Noah Misch, Heikki Linnakangas)

      Several functions, mostly type input functions, calculated an allocation
      size without checking for overflow. If overflow did occur, a too-small
      buffer would be allocated and then written past. (CVE-2014-0064)

    + Prevent overruns of fixed-size buffers (Peter Eisentraut, Jozef Mlich)

      Use strlcpy() and related functions to provide a clear guarantee that
      fixed-size buffers are not overrun. Unlike the preceding items, it is
      unclear whether these cases really represent live issues, ...
