SB2012092802 - Gentoo update for PostgreSQL

Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-0866)

The vulnerability allows a remote #AU# to read and manipulate data.

CREATE TRIGGER in PostgreSQL 8.3.x before 8.3.18, 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 does not properly check the execute permission for trigger functions marked SECURITY DEFINER, which allows remote authenticated users to execute otherwise restricted triggers on arbitrary data by installing the trigger on an attacker-owned table.

2) Input validation error (CVE-ID: CVE-2012-0867)

The vulnerability allows a remote non-authenticated attacker to corrupt data.

PostgreSQL 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 truncates the common name to only 32 characters when verifying SSL certificates, which allows remote attackers to spoof connections when the host name is exactly 32 characters.

3) SQL injection (CVE-ID: CVE-2012-0868)

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

CRLF injection vulnerability in pg_dump in PostgreSQL 8.3.x before 8.3.18, 8.4.x before 8.4.11, 9.0.x before 9.0.7, and 9.1.x before 9.1.3 allows user-assisted remote attackers to execute arbitrary SQL commands via a crafted file containing object names with newlines, which are inserted into an SQL script that is used when the database is restored.

4) Cryptographic issues (CVE-ID: CVE-2012-2143)

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The crypt_des (aka DES-based crypt) function in FreeBSD before 9.0-RELEASE-p2, as used in PHP, PostgreSQL, and other products, does not process the complete cleartext password if this password contains a 0x80 character, which makes it easier for context-dependent attackers to obtain access via an authentication attempt with an initial substring of the intended password, as demonstrated by a Unicode password. As per: http://git.php.net/?p=php-src.git;a=commitdiff;h=aab49e934de1fff046e659cbec46e3d053b41c34 and http://git.php.net/?p=php-src.git;a=commitdiff_plain;h=aab49e934de1fff046e659cbec46e3d053b41c34 PHP 5.3.13 and earlier are vulnerable.

5) Resource management error (CVE-ID: CVE-2012-2655)

The vulnerability allows a remote #AU# to perform service disruption.

PostgreSQL 8.3.x before 8.3.19, 8.4.x before 8.4.12, 9.0.x before 9.0.8, and 9.1.x before 9.1.4 allows remote authenticated users to cause a denial of service (server crash) by adding the (1) SECURITY DEFINER or (2) SET attributes to a procedural language's call handler.

6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-3488)

The vulnerability allows a remote #AU# to read and manipulate data.

The libxslt support in contrib/xml2 in PostgreSQL 8.3 before 8.3.20, 8.4 before 8.4.13, 9.0 before 9.0.9, and 9.1 before 9.1.5 does not properly restrict access to files and URLs, which allows remote authenticated users to modify data, obtain sensitive information, or trigger outbound traffic to arbitrary external hosts by leveraging (1) stylesheet commands that are permitted by the libxslt security options or (2) an xslt_process feature, related to an XML External Entity (aka XXE) issue.

7) Input validation error (CVE-ID: CVE-2012-3489)

The vulnerability allows a remote #AU# to gain access to sensitive information.

The xml_parse function in the libxml2 support in the core server component in PostgreSQL 8.3 before 8.3.20, 8.4 before 8.4.13, 9.0 before 9.0.9, and 9.1 before 9.1.5 allows remote authenticated users to determine the existence of arbitrary files or URLs, and possibly obtain file or URL content that triggers a parsing error, via an XML value that refers to (1) a DTD or (2) an entity, related to an XML External Entity (aka XXE) issue.
