PostgreSQL security updates 9.0.5, 8.4.9, 8.3.16 and 8.2.22 (09/11)

Original Release Date: January 19, 2012
Last Revised: March 26, 2013
Number: ASA-2012-009
Risk Level: Low
Advisory Version: 3.0
Advisory Status: Final

1. Overview:

PostgreSQL is an advanced object-relational database management system (DBMS).

The PostgreSQL Global Development Group released security updates for all active branches of PostgreSQL. This update includes a security fix for contrib/pg_crypto's blowfish encryption code which could give wrong results on platforms where char is signed, leading to encrypted passwords being weaker than they should be. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2011-2483 to this issue.

Note: This advisory targets only Avaya products with postgresql packages provided by postgresql.org. Products with postgresql packages provided by Red Hat will be covered by advisories associated with Red Hat Security Advisories (RHSA).

The information about this vulnerability can be found in the release notes issued by PostgreSQL:

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
