PostgreSQL Project reports :

This update fixes CVE-2014-0060, in which PostgreSQL did not properly enforce the WITH ADMIN OPTION permission for ROLE management. Before this fix, any member of a ROLE was able to grant others access to the same ROLE regardless if the member was given the WITH ADMIN OPTION permission. It also fixes multiple privilege escalation issues, including: CVE-2014-0061, CVE-2014-0062, CVE-2014-0063, CVE-2014-0064, CVE-2014-0065, and CVE-2014-0066. More information on these issues can be found on our security page and the security issue detail wiki page.

With this release, we are also alerting users to a known security hole that allows other users on the same machine to gain access to an operating system account while it is doing 'make check' :
CVE-2014-0067. 'Make check' is normally part of building PostgreSQL from source code. As it is not possible to fix this issue without causing significant issues to our testing infrastructure, a patch will be released separately and publicly. Until then, users are strongly advised not to run 'make check' on machines where untrusted users have accounts.

Various vulnerabilities were discovered in PostgreSQL :

  - CVE-2014-0060 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-2014-0061 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-2014-0062 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-2014-0063 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-2014-0064 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-2014-0065 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, since in most cases     there appear to be previous constraints on the size of     the input string. Nonetheless it seems prudent to     silence all Coverity warnings of this type.

  - CVE-2014-0066 Avoid crashing if crypt() returns NULL     (Honza Horak, Bruce Momjian)

    There are relatively few scenarios in which crypt()     could return NULL, but contrib/chkpass would crash if it     did. One practical case in which this could be an issue     is if libc is configured to refuse to execute unapproved     hashing algorithms (e.g., 'FIPS mode').

  - CVE-2014-0067 Document risks of make check in the     regression testing instructions (Noah Misch, Tom Lane)

    Since the temporary server started by make check uses     'trust' authentication, another user on the same machine     could connect to it as database superuser, and then     potentially exploit the privileges of the     operating-system user who started the tests. A future     release will probably incorporate changes in the testing     procedure to prevent this risk, but some public     discussion is needed first. So for the moment, just warn     people against using make check when there are untrusted     users on the same machine.

The PostgreSQL database server was updated to version 9.1.12 to fix various security issues :
