CVE-2013-1900

Status Candidate

Overview

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."

Red Hat Security Advisory 2013-1475-01
Posted Oct 29, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1475-01 - PostgreSQL is an advanced object-relational database management system. 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 or disclosure of certain portions of server memory. A flaw was found in the way the pgcrypto contrib module of PostgreSQL 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.

Mandriva Linux Security Advisory 2013-142
Posted Apr 12, 2013
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-142 - Multiple vulnerabilities has been discovered and corrected in 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 or read sensitive process memory via a crafted SQL command, which triggers an array index error and an out-of-bounds read. 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 , 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). 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. 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 pg_start_backup or pg_stop_backup functions. This advisory provides the latest versions of PostgreSQL that is not vulnerable to these issues.

Ubuntu Security Notice USN-1789-1
Posted Apr 4, 2013
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1789-1 - 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. 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. Various other issues were also addressed.
