samba and samba3x security update (RHSA-2010-0488)

Original Release Date: July 28, 2010
Last Revised: September 14, 2011
Number: ASA-2010-190
Risk Level: High
Advisory Version: 4.0
Advisory Status: Final

1. Overview:

Samba is a suite of programs used by machines to share files, printers, and other information.

An input sanitization flaw was found in the way Samba parsed client data. A malicious client could send a specially-crafted SMB packet to the Samba server, resulting in arbitrary code execution with the privileges of the Samba server (smbd). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2063 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:

Note: This is Low risk for Message Networking and Voice Portal as smbd does not run by default.

2. Avaya System Products with samba and samba3x installed on RHEL4.x or RHEL5.x:

Product: Affected Version(s): Risk Level: Actions:
Avaya Message Networking 3.1, 5.2 Low Upgrade to MN 5.2.2 or later.
Avaya Messaging Storage Server 4.0, 5.x before 5.2 SP4 with Patch 2 High Upgrade to MSS 5.2 SP4 Patch 2 or later.
Avaya Voice Portal 5.0, 5.1 Low Upgrade to VP 5.1.1 or later.

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's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available or the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.

3. Avaya Software-Only Products:

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.
