PostgreSQL Security Updates 9.1.4, 9.0.8, 8.4.12 and 8.3.19 (6/12)

Original Release Date: July 6, 2012
Last Revised: July 6, 2012
Number: ASA-2012-289
Risk Level: Low
Advisory Version: 1.0
Advisory Status: Interim

1. Overview:

PostgreSQL is an advanced Object-Relational database management system (DBMS). 
The PostgreSQL Global Development Group has released security updates for all 
active branches of the PostgreSQL database system, including versions 9.1.4, 
9.0.8, 8.4.12 and 8.3.19.

This update includes security fixes for the following issues:

* A security flaw was found in the way the DES and extended DES based crypt() 
password encryption functions performed encryption of certain keys, when the 
key to be encrypted was provided in the Unicode encoding (certain keys were 
truncated before being DES digested). When the resulting ciphertext for such 
a previously shortened key was used as a pattern in a password protected 
resource, intended to be matched against subsequently encrypted value of the 
password field, retrieved from the user authentication dialog, it could lead 
to authentication bypass. The Common Vulnerabilities and Exposures project 
(cve.mitre.org) has assigned the name CVE-2012-2143 to this issue.

* A security flaw was found in the way PostgreSQL performed inclusion of 
additional procedural language plug-ins support into PostgreSQL server. 
Previously, database administrators were allowed to install trusted procedural 
languages into their databases and the owner of such procedural language 
function were allowed to execute ALTER FUNCTION statement. If a procedural 
language plug-in was enabled on the particular database, an authenticated 
database administrator could use this flaw to cause denial of service 
(PostgreSQL server crash) by adding SECURITY DEFINER or SET attributes to such 
a handler function. The Common Vulnerabilities and Exposures project 
(cve.mitre.org) has assigned the name CVE-2012-2655 to this issue.

The information about these vulnerabilities may be found in the release notes 
issued by PostgreSQL:

    PostgreSQL Security Update 2012-06-04
    release-9.1.4
    release-9.0.8
    release-8.4.12
    release-8.3.19

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).

2. Avaya System Products with affected version(s) of PostgreSQL installed:

Product: 					Affected Version(s): 	Risk 
									Level: 	
Avaya Aura Application Enablement Services 	5.x, 6.x 		Low 		
Avaya Aura Experience Portal 			6.0.x 			Low 		
Avaya Meeting Exchange 				5.x 			Low 		
Avaya Aura Presence Services 			6.x 			Low 		
Avaya Aura Session Manager 			1.1, 5.x, 6.x 		Low 		
Avaya Aura System Manager 			5.x, 6.x 		Low 		
Avaya Voice Portal 				5.x 			Low 		

Actions: See recommended actions below.  This issue will be addressed in 
accordance with section five of Avaya's Product Security Vulnerability Response 
Policy

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:

Vulnerability 	Mitigating Factors
CVE-2012-2143 	There is no Risk for Presence Services, Session Manager and 
                Voice Portal since the crypt encryption function is not used.
		This is a Low Risk for Application Enablement Services, 
		Experience Portal, Meeting Exchange and System Manager because 
		access is restricted to local system administrators only.

CVE-2012-2655 	This is a Low Risk for all products because only local 
		adminstrators could perform this attack, and doing so would not 
		give them any additional privileges than they already have.

3. Additional Information:

Additional information may also be available via the Avaya support website and 
through your Avaya account representative. Please contact your Avaya product 
support representative, or dial 1-800-242-2121, with any questions.
