annotate src/http/modules/ngx_http_scgi_module.c @ 4534:fb322541c548 stable-1.0
Merge of r4530, r4531: null character fixes.
*) Fixed incorrect ngx_cpystrn() usage in ngx_http_*_process_header().
This resulted in a disclosure of previously freed memory if upstream
server returned specially crafted response, potentially exposing
sensitive information.
Reported by Matthew Daley.
*) Headers with null character are now rejected.
Headers with NUL character aren't allowed by HTTP standard and may cause
various security problems. They are now unconditionally rejected.
