Public bug reported:
The system is Ubuntu 16.04 with ESM support.
After the update (28.5.2022) of openssl and libssl1.0.0 packages from
1.0.2g-1ubuntu4.20+esm2 to 1.0.2g-1ubuntu4.20+esm3 the php function
openssl_get_cipher_methods (php7 from the distribution) is broken.
It randomly returns empty array when called.
Testing from php-cli it always returns proper data.
Testing with web server most of the times it returns an empty array.
Tested with apache + mod-php and apache + php-fpm.
Downgrading to versions to 1.0.2g-1ubuntu4.20 fixes the problem.
This downgrade makes the systems work, but introduces security risks.
An example code to reproduce the issue:
--------------------------------
<?php
$ciphers = openssl_get_cipher_methods();
$ciphers_and_aliases = openssl_get_cipher_methods(true);
$cipher_aliases = array_diff($ciphers_and_aliases, $ciphers);
echo implode($ciphers);
print_r($ciphers);
print_r($cipher_aliases);
?>
