Multiple vulnerabilities has been discovered and corrected in postgresql :

PostgreSQL 9.2.x before 9.2.3, 9.1.x before 9.1.8, 9.0.x before 9.0.12, 8.4.x before 8.4.16, and 8.3.x before 8.3.23 does not properly declare the enum_recv function in backend/utils/adt/enum.c, which causes it to be invoked with incorrect arguments and allows remote authenticated users to cause a denial of service (server crash) or read sensitive process memory via a crafted SQL command, which triggers an array index error and an out-of-bounds read (CVE-2013-0255).

Argument injection vulnerability in PostgreSQL 9.2.x before 9.2.4, 9.1.x before 9.1.9, and 9.0.x before 9.0.13 allows remote attackers to cause a denial of service (file corruption), and allows remote authenticated users to modify configuration settings and execute arbitrary code, via a connection request using a database name that begins with a - (hyphen) (CVE-2013-1899).

PostgreSQL 9.2.x before 9.2.4, 9.1.x before 9.1.9, 9.0.x before 9.0.13, and 8.4.x before 8.4.17, when using OpenSSL, generates insufficiently random numbers, which might allow remote authenticated users to have an unspecified impact via vectors related to the contrib/pgcrypto functions. (CVE-2013-1900).

PostgreSQL 9.2.x before 9.2.4 and 9.1.x before 9.1.9 does not properly check REPLICATION privileges, which allows remote authenticated users to bypass intended backup restrictions by calling the (1) pg_start_backup or (2) pg_stop_backup functions (CVE-2013-1901).

This advisory provides the latest versions of PostgreSQL that is not vulnerable to these issues.

The remote host is running a version of Mac OS X 10.8.x that is prior to 10.8.5. The newer version contains multiple security-related fixes for the following components :

  - Apache
  - Bind
  - Certificate Trust Policy
  - CoreGraphics
  - ImageIO
  - Installer
  - IPSec
  - Kernel
  - Mobile Device Management
  - OpenSSL
  - PHP
  - PostgreSQL
  - Power Management
  - QuickTime
  - Screen Lock
  - sudo

This update also addresses an issue in which certain Unicode strings could cause applications to unexpectedly quit.

Note that successful exploitation of the most serious issues could result in arbitrary code execution.

The remote Mac OS X 10.8 host has a version of OS X Server installed that is prior to 2.2.2. It is, therefore, affected by the following vulnerabilities :

  - Two vulnerabilities exist in the included ClamAV     software, the most serious of which could allow an     attacker to execute arbitrary code remotely.
    (CVE-2013-2020 / CVE-2013-2021)

  - Three vulnerabilities exist in the included PostgreSQL     software, the most serious of which could result in     data corruption or privilege escalation.
    (CVE-2013-1899 / CVE-2013-1900 / CVE-2013-1901)

  - Multiple cross-site scripting issues exist in the     included Wiki Server software (CVE-2013-1034)

The version of PostgreSQL installed on the remote host is 9.1.x prior to 9.1.9 or 9.2.x prior to 9.2.4.  As such, it is potentially affected by a denial of service vulnerability.  An unprivileged user can run commands that could interfere with in-progress backups.

- Update to PostgreSQL 9.2.4, for various fixes described     at     http://www.postgresql.org/docs/9.2/static/release-9-2-4.
    html including the fixes for CVE-2013-1899,     CVE-2013-1900, CVE-2013-1901

  - fix build for aarch64 and ppc64p7

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

postgresql was updated to version 9.1.9 (bnc#812525) :

  - CVE-2013-1899: Fix insecure parsing of server     command-line switches. A connection request containing a     database name that begins with '-' could be crafted to     damage or destroy files within the server's data     directory, even if the request is eventually rejected.

  - CVE-2013-1900: Reset OpenSSL randomness state in each     postmaster child process. This avoids a scenario wherein     random numbers generated by 'contrib/pgcrypto' functions     might be relatively easy for another database user to     guess. The risk is only significant when the postmaster     is configured with ssl = on but most connections don't     use SSL encryption.

  - CVE-2013-1901: Make REPLICATION privilege checks test     current user not authenticated user. An unprivileged     database user could exploit this mistake to call     pg_start_backup() or pg_stop_backup(), thus possibly     interfering with creation of routine backups.

PostgreSQL project reports :

The PostgreSQL Global Development Group has released a security update to all current versions of the PostgreSQL database system, including versions 9.2.4, 9.1.9, 9.0.13, and 8.4.17. This update fixes a high-exposure security vulnerability in versions 9.0 and later. All users of the affected versions are strongly urged to apply the update
*immediately*.

A major security issue (for versions 9.x only) fixed in this release, [CVE-2013-1899](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013
-1899), makes it possible for a connection request containing a database name that begins with '-' to be crafted that can damage or destroy files within a server's data directory. Anyone with access to the port the PostgreSQL server listens on can initiate this request.
This issue was discovered by Mitsumasa Kondo and Kyotaro Horiguchi of NTT Open Source Software Center.

Two lesser security fixes are also included in this release :
[CVE-2013-1900](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013
-1900), wherein random numbers generated by contrib/pgcrypto functions may be easy for another database user to guess (all versions), and [CVE-2013-1901](http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013
-1901), which mistakenly allows an unprivileged user to run commands that could interfere with in-progress backups (for versions 9.x only).

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

    Multiple vulnerabilities have been discovered in PostgreSQL. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote authenticated attacker may be able to create a Denial of       Service condition, bypass security restrictions, or have other       unspecified impact.
  Workaround :

    There is no known workaround at this time.

Mitsumasa Kondo and Kyotaro Horiguchi discovered that PostgreSQL incorrectly handled certain connection requests containing database names starting with a dash. A remote attacker could use this flaw to damage or destroy files within a server's data directory. This issue only applied to Ubuntu 11.10, Ubuntu 12.04 LTS, and Ubuntu 12.10.
(CVE-2013-1899)

Marko Kreen discovered that PostgreSQL incorrectly generated random numbers. An authenticated attacker could use this flaw to possibly guess another database user's random numbers. (CVE-2013-1900)

Noah Misch discovered that PostgreSQL incorrectly handled certain privilege checks. An unprivileged attacker could use this flaw to possibly interfere with in-progress backups. This issue only applied to Ubuntu 11.10, Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2013-1901).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update to version 9.1.9 fixes :

  - Fix insecure parsing of server command-line switches.
    (CVE-2013-1899)

  - Reset OpenSSL randomness state in each postmaster child     process. (CVE-2013-1900)

  - Make REPLICATION privilege checks test current user not     authenticated user. (CVE-2013-1901)
