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.

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.

PostgreSQL was updated to version 9.1.8 (bnc#802679) :

  - Prevent execution of enum_recv from SQL (CVE-2013-0255).

  - Fix multiple problems in detection of when a consistent     database state has been reached during WAL replay

  - Update minimum recovery point when truncating a relation     file

  - Fix recycling of WAL segments after changing recovery     target timeline

  - Fix missing cancellations in hot standby mode

  - See the release notes for the rest of the changes:
    http://www.postgresql.org/docs/9.1/static/release-9-1-8.
    html /usr/share/doc/packages/postgresql/HISTORY

  - Remove postgresql91-full.spec.in and use     postgresql91.spec as the master for generating     postgresql91-libs.spec.

An array index error, leading to a heap-based out-of-bounds buffer read flaw, was found in the way PostgreSQL performed certain error processing using enumeration types. An unprivileged database user could issue a specially crafted SQL query that, when processed by the server component of the PostgreSQL service, would lead to a denial of service (daemon crash) or disclosure of certain portions of server memory. (CVE-2013-0255)

A flaw was found in the way the pgcrypto contrib module of PostgreSQL (re)initialized its internal random number generator. This could lead to random numbers with less bits of entropy being used by certain pgcrypto functions, possibly allowing an attacker to conduct other attacks. (CVE-2013-1900)

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2013-1475 advisory.

    [8.4.18-1]
    - Update to PostgreSQL 8.4.18, for various fixes described at       http://www.postgresql.org/docs/8.4/static/release-8-4-14.html       http://www.postgresql.org/docs/8.4/static/release-8-4-15.html       http://www.postgresql.org/docs/8.4/static/release-8-4-16.html       http://www.postgresql.org/docs/8.4/static/release-8-4-17.html       http://www.postgresql.org/docs/8.4/static/release-8-4-18.html       including fixes for CVE-2013-0255, CVE-2013-1900 (#1017837)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

Versions of PostgreSQL earlier than 8.3.23, 8.4.16, 9.0.12, 9.1.8, 9.2.3 and are potentially affected by a denial of service vulnerability due to a flaw in the enum_recv() functin of 'backend/utils/adt/enum.c'. By exploiting this flaw, a remote attacker could crash the affected application

PostgreSQL has been updated to version 8.3.23 which fixes various bugs and one security issue.

The security issue fixed in this release, CVE-2013-0255, allowed a previously authenticated user to crash the server by calling an internal function with invalid arguments. This issue was discovered by independent security researcher Sumit Soni this week and reported via Secunia SVCRP, and we are grateful for their efforts in making PostgreSQL more secure.

http://www.postgresql.org/about/news/1446/

PostgreSQL has been updated to version 9.1.8 which fixes various bugs and one security issue.

The security issue fixed in this release, CVE-2013-0255, allowed a previously authenticated user to crash the server by calling an internal function with invalid arguments. This issue was discovered by the independent security researcher Sumit Soni this week and reported via Secunia SVCRP, and we are grateful for their efforts in making PostgreSQL more secure.

More information can be found at

http://www.postgresql.org/about/news/1446/

Sumit Soni discovered that PostgreSQL, an object-relational SQL database, could be forced to crash when an internal function was called with invalid arguments, resulting in denial of service.

The version of PostgreSQL installed on the remote host is 8.3.x prior to 8.3.23, 8.4.x prior to 8.4.16, 9.0.x prior to 9.0.12, 9.1.x prior to 9.1.8 or 9.2 prior to 9.2.3.  It is, therefore, potentially affected by a denial of service vulnerability due to a flaw in the enum_recv() function of 'backend/utils/adt/enum.c'.  By exploiting this flaw, a remote attacker could crash the affected application.

- Update to new upstream releases, to fix CVE-2013-0255     and other issues described at     http://www.postgresql.org/docs/9.2/static/release-9-2-3.
