DragonFly bugs List (threaded) for 2008-05
Re: [issue1006] digest is down; suggestions welcome
It seems there was an off-by-one error in the strspn code in our libc.
The buffer was a byte too small and resulted in overwriting the saved
ebx which was the offset to the GOT -- but only if strspn was used
with a \xff in the second string.
I have a patch here:
I've verified it fixes the PHP problem. Also, I tested it against a
small program that called strspn with a \xff in the second string and
verified that ebx was correctly restored (unlike prior to the patch).
