PostgreSQL is an advanced Object-Relational database management system (DBMS). The PostgreSQL Global Development Group has released a security update to all current versions of the PostgreSQL database system, including versions 9.2.3, 9.1.8, 9.0.12, 8.4.16, and 8.3.23.
A flaw was found in PostgreSQL where it 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 (server crash) or read sensitive process memory via a crafted SQL command, which triggers an array index error and an out-of-bounds read. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0255 to this issue.
The information about these vulnerabilities may be found in the release notes issued by PostgreSQL.org:
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).

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.
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:
|CVE-2013-0255||There is no risk to Application Enablement Services as the affected package versions are not installed.
This is a Low risk to Experience Portal, Meeting Exchange, Presence Services, Session Manager, System Manager and Voice Portal as remote access to the PostgreSQL database is not allowed by default or requires local administrative access to exploit and would not provide additional capabilities.
