Hi list, Read about potential UAF in PHP and Ruby via regex library "oniguruma" (for example here: https://thehackernews.com/2019/09/php-programming-language.html) However, I didn't find default PHP and Ruby vulnerable: https://github.com/kkos/oniguruma/issues/153 My investigation showed the onig_new_deluxe() is not used by default. However, modified PHP to use it and fuzzed it and was able to reproduce UAF in 7 mins :) Write me if I am wrong. Would like to investigate this great bug. Thanks, Marcin _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
