GCVE-110-MAGEIA-2017-28

The "attribute uniqueness" plugin did not properly NULL-terminate an array when building up its configuration if a so called 'old-style' configuration was being used. An attacker, authenticated, but possibly also unauthenticated, could possibly force the plugin to read beyond allocated memory and trigger a segfault. The crash could also possibly be triggered accidentally (CVE-2017-2591).
