Updated postgresql packages fix multiple security vulnerabilities :

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).

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).

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).

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).

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).

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-2014-0065).

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-2014-0066).

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 (CVE-2014-0067).

A user with limited clearance on a table might have access to information in columns without SELECT rights on through server error messages (CVE-2014-8161).

The function to_char() might read/write past the end of a buffer. This might crash the server when a formatting template is processed (CVE-2015-0241).

The pgcrypto module is vulnerable to stack buffer overrun that might crash the server (CVE-2015-0243).

Emil Lenngren reported that an attacker can inject SQL commands when the synchronization between client and server is lost (CVE-2015-0244).

This update provides PostgreSQL versions 9.3.6 and 9.2.10 that fix these issues, as well as several others.

The remote Mac OS X host has a version of OS X Server installed that is prior to version 4.0.  It is, therefore, affected by the following vulnerabilities :

  - There are multiple vulnerabilities within the included     BIND, the most serious of which can lead to a denial of     service. (CVE-2013-3919, CVE-2013-4854, CVE-2014-0591)

  - There are multiple vulnerabilities within the included     LibYAML for the Profile Manager and ServerRuby, the most     serious of which can lead to arbitrary code execution.
    (CVE-2013-4164, CVE-2013-6393)

  - There are multiple vulnerabilities within the included     PostgreSQL, the most serious of which can lead to     arbitrary code execution. (CVE-2014-0060, CVE-2014-0061,     CVE-2014-0062, CVE-2014-0063, CVE-2014-0064,     CVE-2014-0065, CVE-2014-0066)

  - An error exists related to the way SSL 3.0 handles     padding bytes when decrypting messages encrypted using     block ciphers in cipher block chaining (CBC) mode. A     man-in-the-middle attacker can decrypt a selected byte     of a cipher text in as few as 256 tries if they are able     to force a victim application to repeatedly send the     same data over newly created SSL 3.0 connections. This     is also known as the 'POODLE' issue. (CVE-2014-3566)

  - A cross-site scripting flaw exists in the Xcode Server     due to not properly validating input before returning it     to the user. This can allow a remote attacker, using a     specially crafted request, to execute code within the     browser / server trust relationship. (CVE-2014-4406)

  - A SQL injection flaw exists in the Wiki Server due to     not properly sanitizing user input before using it in     SQL queries. This can allow a remote attacker, using a     specially crafted request, to inject or manipulate SQL     queries, thus allowing the manipulation or disclosure     of arbitrary data. (CVE-2014-4424)

  - A restriction bypass flaw exists in the Mail Server due     to SCAL changes being cached and not enforced until the     service had restarted. This can allow an authenticated     remote attacker to bypass those restrictions.
    (CVE-2014-4446)

  - A password disclosure flaw exists in the Profile Manager     due to passwords being potentially saved to a file when     editing or setting up a profile. This can allow a local     attacker to gain access to password information.
    (CVE-2014-4447)

The remote host is affected by the vulnerability described in GLSA-201408-15 (PostgreSQL: Multiple vulnerabilities)

    There is no known workaround at this time.

Updated postgresql84 and postgresql packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 and 6 respectively.

The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

PostgreSQL is an advanced object-relational database management system (DBMS).

Multiple stack-based buffer overflow flaws were found in the date/time implementation of PostgreSQL. An authenticated database user could provide a specially crafted date/time value that, when processed, could cause PostgreSQL to crash or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL.
(CVE-2014-0063)

Multiple integer overflow flaws, leading to heap-based buffer overflows, were found in various type input functions in PostgreSQL.
An authenticated database user could possibly use these flaws to crash PostgreSQL or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2014-0064)

Multiple potential buffer overflow flaws were found in PostgreSQL. An authenticated database user could possibly use these flaws to crash PostgreSQL or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2014-0065)

It was found that granting a SQL role to a database user in a PostgreSQL database without specifying the 'ADMIN' option allowed the grantee to remove other users from their granted role. An authenticated database user could use this flaw to remove a user from a SQL role which they were granted access to. (CVE-2014-0060)

A flaw was found in the validator functions provided by PostgreSQL's procedural languages (PLs). An authenticated database user could possibly use this flaw to escalate their privileges. (CVE-2014-0061)

A race condition was found in the way the CREATE INDEX command performed multiple independent lookups of a table that had to be indexed. An authenticated database user could possibly use this flaw to escalate their privileges. (CVE-2014-0062)

It was found that the chkpass extension of PostgreSQL did not check the return value of the crypt() function. An authenticated database user could possibly use this flaw to crash PostgreSQL via a NULL pointer dereference. (CVE-2014-0066)
