The sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root.
A privilege escalation flaw was found in the way sudo handled the sudoedit pseudo-command. If a local user were authorized by the sudoers file to use this pseudo-command, they could possibly leverage this flaw to execute arbitrary code with the privileges of the root user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0426 to this issue.
The sudo utility did not properly initialize supplementary groups when the "runas_default" option (in the sudoers file) was used. If a local user were authorized by the sudoers file to perform their sudo commands under the account specified with "runas_default", they would receive the root user's supplementary groups instead of those of the intended target user, giving them unintended privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-0427 to this issue.

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.
Avaya software-only products operate on general-purpose operating systems.

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.
