Descriptions

A typo in Linux kernel 2.6 before 2.6.21-rc6 and 2.4 before 2.4.35 causes RTA_MAX to be used as an array size instead of RTN_MAX, which leads to an "out of bound access" by the (1) dn_fib_props (dn_fib.c, DECNet) and (2) fib_props (fib_semantics.c, IPv4) functions.

Un error tipográfico en el Kernel de Linux versión 2.6 anterior a 2.6.21-rc6 y versión 2.4 anterior a 2.4.35 hace que RTA_MAX se utilice como un tamaño de matriz en lugar de RTN_MAX, lo que conlleva a un "out of bound access" mediante las funciones (1) dn_fib_props (dn_fib.c, DECNet) y (2) fib_props (fib_semantics.c, IPv4).
