lib/libc/stdlib: lsearch.c
Log message:
lsearch(3): append key to array with memmove(3) instead of memcpy(3)
If the key overlaps the end of the array, memcpy(3) mutates the key
and copies a corrupted value into the end of the array.
If we use memmove(3) instead we at least end up with a clean copy of
the key at the end of the array. This is closer to the intended
behavior.
With input from millert@ and deraadt@.
