Description
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.
Affected configurations
• simplesamlphp simplesamlphp (< 1.15.2)
• debian debian linux 7.0
• debian debian linux 8.0
• debian debian linux 9.0
