The PostgreSQL Global Development Group has released security updates for all active branches of the PostgreSQL database system, including versions 9.1.5, 9.0.9, 8.4.13 and 8.3.20. This update patches security holes associated with libxml2 and libxslt, similar to those affecting other open source projects.
This security release fixes a vulnerability in the built-in XML functionality, and a vulnerability in the XSLT functionality supplied by the optional XML2 extension. Both vulnerabilities allow reading of arbitrary files by any authenticated database user, and the XSLT vulnerability allows writing files as well. The fixes cause limited backwards compatibility issues. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2012-3488 and CVE-2012-3489 to these issues.
More information about these vulnerabilities can be found in the release notes issued by PostgreSQL.org:

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:
|These are a low risk to Application Enablement Services, Experience Portal, Presence Services, Session Manager and Voice Portal as the affected XML and XSLT functionality is not used by default.
These are a medium risk for Meeting Exchange and System Manager due to the potential for an authenticated database user to access files which they normally would not have acesss to, effectively a privilege escalation.
