CVE-2010-1439

Status: ModifiedLow (3.6)—

yum-rhn-plugin in Red Hat Network Client Tools (aka rhn-client-tools) on Red Hat Enterprise Linux (RHEL) 5 and Fedora uses world-readable permissions for the /var/spool/up2date/loginAuth.pkl file, which allows local users to access the Red Hat Network profile, and possibly prevent future security updates, by leveraging authentication data from this file.

CVSS
