PostgreSQL is an advanced object-relational database management system (DBMS).
An array index error, leading to a heap-based out-of-bounds buffer read flaw, was found in the way PostgreSQL performed certain error processing using enumeration types. An unprivileged database user could issue a specially crafted SQL query that, when processed by the server component of the PostgreSQL service, would lead to a denial of service (daemon crash) or disclosure of certain portions of server memory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0255 to this issue.
A flaw was found in the way the pgcrypto contrib module of PostgreSQL (re)initialized its internal random number generator. This could lead to random numbers with less bits of entropy being used by certain pgcrypto functions, possibly allowing an attacker to conduct other attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-1900 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends following the 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 the System Product operating system or application should not be modified 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:
|There is no risk for CMS because only the postgresql-libs package is installed and not postgresql, which is needed to exploit these issues.
There is no risk for AES, Communication Manager, Conferencing, Conferencing SE, Messaging and IPOAS 6.x, 7.x, 8.x because these products use RHEL5. Only the postgresql84 packages are affected for RHEL5 and these packages are not installed.
The risk is rated Low for IP Office Server Edition and Application Server 9.0 because only privileged users have system and database access and the exploit would not provide any additional capabilities.
The risk is rated Medium for Utility Services because of the possibility of a Denial of Service or information disclosure.
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
