just installed php-fpm + nginx on a 20.04 system today (2021-12-05) which installed 7.4.3-4ubuntu2.7 , which seems vulnerable, POC code still causes segfaults: https://github.com/cfreal/exploits/blob/master/php-SplDoublyLinkedList- offsetUnset/exploit.php
i don't think this is fixed yet? at least not on 20.04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1948957 Title: CVE-2021-21703: PHP-FPM oob R/W in root process leading to privilege escalation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/php7.4/+bug/1948957/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
