Fixes GH-20974 Co-authored-by: Ilija Tovilo <ilija.tovilo@me.com>
php_filter_encode_url() initialized its 256-byte "must encode" table with memset(tmp, 1, sizeof(tmp) - 1), leaving tmp[255] uninitialized. Whether 0xFF got percent-encoded then depended on stack garbage; valgrind reports the read as a conditional jump on an uninitialised value. Initialize the whole table. Closes GH-22762
* PHP-8.4: ext/filter: encode 0xFF in FILTER_SANITIZE_ENCODED
* PHP-8.5: ext/filter: encode 0xFF in FILTER_SANITIZE_ENCODED
Commit 3dcdb98 routed the user_agent option through a truncate-and-warn check, but the Content-Type context option, the soapaction and the cookie names and values reach the same request buffer unchecked, so a CR/LF in any of them still injects arbitrary request headers. Emit all of them through that same check. The helper now takes an explicit length so the char* soapaction can share it. Close GH-22781
