rhn-client-tools security update (RHSA-2010-0449)

Original Release Date: July 6, 2010
Last Revised: January 18, 2011
Number: ASA-2010-166
Risk Level: Low
Advisory Version: 2.0
Advisory Status: Interim

1. Overview:

Red Hat Network Client Tools provide programs and libraries that allow your system to receive software updates from the Red Hat Network (RHN).

It was discovered that rhn-client-tools set insecure permissions on the loginAuth.pkl file, used to store session credentials for authenticating connections to Red Hat Network servers. A local, unprivileged user could use these credentials to download packages from the Red Hat Network. They could also manipulate package or action lists associated with the system's profile. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-1439 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.

Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
