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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0663 to this issue.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-1341 to this issue.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-3963 to this issue.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4098 to this issue.
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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0922 to this issue.
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
