It was discovered that consolehelper configuration files (/etc/security/console.apps/system-config-network) as shipped in Fedora 8 system-config-network packages allowed any local console user to start system-config-network configuration program with root privileges by providing only user password, not administrator password. This allows any user with local console access to change network configuration of the host.

Configuration file did not include USER=root directive and tried to include file config-util, which does not exist on Fedora 8 and is only provided by usermode package in Fedora 9. Without USER= specification, consolehelper prompted user for user password instead of intended root password.

Integer overflow in the rbaryfill function in array.c in Ruby before revision 17756 allows context-dependent attackers to cause a denial of service (crash) or possibly have unspecified other impact via a call to the Array#fill method with a start (aka beg) argument greater than ARYMAXSIZE. NOTE: this issue exists because of an incomplete fix for other closely related integer overflows.
