sudo security update (RHSA-2010-0675)

Original Release Date: October 4, 2010
Last Revised: August 29, 2012
Number: ASA-2010-261
Risk Level: Low
Advisory Version: 6.0
Advisory Status: Final

1. Overview:

The sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root.

A flaw was found in the way sudo handled Runas specifications containing both a user and a group list. If a local user were authorized by the sudoers file to perform their sudo commands with the privileges of a specified user and group, they could use this flaw to run those commands with the privileges of either an arbitrary user or group on the system. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-2956 to this issue.

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

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.
