RHSA-2009:1067: Red Hat Application Stack v2.3 security and enhancement update



Red Hat Application Stack v2.3 is now available. This update fixes several security issues and adds various enhancements. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Red Hat Application Stack v2.3 is an integrated open source application stack, that includes Red Hat Enterprise Linux 5 and JBoss Enterprise Application Platform (EAP). JBoss EAP is provided through the JBoss EAP channels on the Red Hat Network. This update fixes the following security issues: A heap-based buffer overflow flaw was discovered in the perl-DBD-Pg pg_getline function implementation. If the pg_getline or getline functions read large, untrusted records from a database, it could cause an application using these functions to crash or, possibly, execute arbitrary code. (CVE-2009-0663) Note: After installing this update, pg_getline may return more data than specified by its second argument, as this argument will be ignored. This is consistent with current upstream behavior. Previously, the length limit (the second argument) was not enforced, allowing a buffer overflow. A memory leak flaw was found in the perl-DBD-Pg function performing the de-quoting of BYTEA type values acquired from a database. An attacker able to cause an application using perl-DBD-Pg to perform a large number of SQL queries returning BYTEA records, could cause the application to use excessive amounts of memory or, possibly, crash. (CVE-2009-1341) MySQL was updated to version 5.0.79, fixing the following security issues: A flaw was found in the way MySQL handles an empty bit-string literal. A remote, authenticated attacker could crash the MySQL server daemon (mysqld) if they used an empty bit-string literal in an SQL statement. This issue only caused a temporary denial of service, as the MySQL daemon was automatically restarted after the crash. (CVE-2008-3963) It was discovered that the Red Hat Security Advisory RHSA-2008:0505, for Red Hat Application Stack v2.1, provided an incomplete fix for the flaw where MySQL did not correctly check directories used as arguments for the DATA DIRECTORY and INDEX DIRECTORY directives. Using this flaw, an authenticated attacker could elevate their access privileges to tables created by other database users. Note: This attack does not work on existing tables. An attacker can only elevate their access to another user's tables as the tables are created. As well, the names of these created tables need to be predicted correctly for this attack to succeed. (CVE-2008-4098) PostgreSQL was updated to version 8.2.13, fixing the following security issue: A flaw was found in the way PostgreSQL handles encoding conversion. A remote, authenticated user could trigger an encoding conversion failure, possibly leading to a temporary denial of service. (CVE-2009-0922) Also, the following packages have been updated: * httpd to 2.2.11 * mysql-connector-odbc to 3.51.27r695 * perl-DBD-MySQL to 4.010-1.el5s2 * php to 5.2.9 * postgresql-jdbc to 8.2.509 * postgresqlclient81 to 8.1.17 All users should upgrade to these updated packages, which resolve these issues. Users must restart the individual services, including postgresql, mysqld, and httpd, for this update to take effect.
