privilege escalation via incorrect view frm parsing
Impact
An account with the CREATE USER and a CREATE VIEW with GRANT OPTION can embed new lines and view metadata into the user name and create a view where part of the user name will be treated as view metadata, possibly causing privilege escalation.
Patches
Fixed in 10.6.28, 10.11.19, 11.4.13, 11.8.9, 12.3.3, 13.0.2.
Workarounds
CREATE USER is a high privileged administrative operation, if only high privileged users have it, they won't have a higher-privileged account to escalate to. In most installation this is already the case.
