[Bug 1626886] [NEW] libssl 1.0.2g-1ubuntu4.4 may cause Apache2 with libapache2-mod-php7.0 to crash

 

Public bug reported:

I started getting apache2 crashes at the same time as I started getting
PHP 7.0 CLI crashes, after my openssl packages were updated to the
latest xenial-security version by unattended-upgrades.

I traced the PHP CLI crashes to server cert validation starting to crash
after updating to libssl1.0.0 1.0.2g-1ubuntu4.4 here
https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1626883

Not sure if this crash is the exact same thing or something else, but
the web server starting to crash after an automatic security update is
very troublesome in any case...
