CVE-2018-6521  (opens in a new tab)

How to fix?

Upgrade Debian:8 simplesamlphp to version 1.13.1-2+deb8u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream simplesamlphp package and not the simplesamlphp package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

The sqlauth module in SimpleSAMLphp before 1.15.2 relies on the MySQL utf8 charset, which truncates queries upon encountering four-byte characters. There might be a scenario in which this allows remote attackers to bypass intended access restrictions.
