Description Adam Mariš 2015-09-07 15:11:15 UTC 
If spl_autoload doesn't load anything valid, it tries to throw an exception, possibly using null pointer, causing the crash.

Comment 5 Tomas Hoger 2015-09-30 07:44:05 UTC 
This is not considered to be a security vulnerability - crash is triggered by specially-crafted / malicious PHP script, hence trust boundary is not crossed.
