yum-rhn-plugin on RHEL 5 and Fedora exposes login data

CVE-2010-1439 · published 16 years ago
Summary

The yum-rhn-plugin on Red Hat Enterprise Linux 5 and Fedora stores a file called loginAuth.pkl with permissions that let any user on the system read it. This lets a local user see the Red Hat Network login details and could stop the system from receiving future updates. Fix it by resetting the file permissions to restrict access or applying the latest security update from Red Hat.
