Subject: [PATCH] Rewrite: fixed escaping and possible buffer overrun
The following code resulted in incorrect escaping of $1 and possible
segfault:
location / {
rewrite ^(.*) /new?c=1;
set $myvar $1;
return 200 $myvar;
}
If there were arguments in a rewrite's replacement string, the is_args flag
was set and incorrectly never cleared. This resulted in escaping applied
to any captures evaluated afterwards in set or if. Additionally buffer was
allocated by ngx_http_script_complex_value_code() without escaping expected,
thus this also resulted in buffer overrun and possible segfault.
A similar issue was fixed in 74d939974d43.
Reported by Leo Lin.
