 Description: 
+ A typo in Linux kernel 2.6 before 2.6.21-rc6 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.
 Ubuntu-Description: 
+ The IPv4 and DECnet network protocol handlers misdeclared an array
+ variable so that it became smaller than intended. By sending crafted
+ packets over a netlink socket, a local attacker could exploit this
+ to crash the kernel.
