The default configuration of consolehelper in system-config-network before 1.5.10-1 on Fedora 8 lacks the USER=root directive, which allows local users of the workstation console to gain privileges and change the network configuration.

ruby: integer overflows in rb_ary_fill() / Array#fill

Integer overflow in the rb_ary_fill 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 ARY_MAX_SIZE. NOTE: this issue exists because of an incomplete fix for other closely related integer overflows.
