2019-02-07Fix parsing overflow in unformat_mac_address_t()Benoît Ganne1-3/+3
'%x' unformat specifier expects a pointer to a 4-byte object and will overflow when using a pointer to a 1-byte object. Use '%X' instead which allows to pass the size of the object alongside its pointer. The bug was exposed with the following commands: ~# make run DBGvpp# loop create loop0 DBGvpp# set ip6 neigh loop0 3001::2 a:a:a:a:a:a DBGvpp# show ip6 neigh Time Address Flags Link layer Interface 35.7743 ::2 D 0a:0a:0a:0a:0a:0a loop0 ^^^ wrong address: should be 3001::2 Note that the bug impact depends from the parsing order and memory layout.
